How to identify antique & modern reproductions of cut nails.
This article includes an identification key to specific types & dimensions of cut nails, followed with examples and description of hand-wrought heads, derived from Nelson and other historical researchers of nails and fasteners and using additional nail identification key photos based on Tremont Nail Co.'s., History of Cut Nails in America, cited in detail here.
This article series describes and illustrates antique & modern hardware: door knobs, latches, hinges, window latches, hardware, nails & screws can help determine a building's age by noting how those parts were fabricated: by hand, by machine, by later generations of machine.

Cut nails are metal nails, usually iron, occasionally brass or bronze, that were "cut" from a large flat rectangular metal plate by using a huge slicing blade that could cut red hot metal. By "wiggling" the nail plate from side to side as it was fed into the shear or cutting tool the result was a tapered nail blank that virtually eliminated the need for hand-forged nail pointing.
The earliest cut nails cut from blanks were made using a hand operated cutting machine and the nail heads then forged by hand.
Later inventions included a heading die that could form the head on a cut nail by an additional machine step.
Modern cut nails are made by powered machines that produce cut nails at much larger volume and greater speed.
If your question is just about the age of an old nail or spike, see the key found
at NAIL AGE DETERMINATION KEY but remember that knowing the type of nail also helps identify its historic context or use and thus is also a clue to its age.
For a chronological history of types of nails from earliest time
Above, excerpted and annotated from Tremont's panel of antique cut nails produced in America, we include some example cut nail dimensions.

You can obtain the lengths of other nails in this key by comparing the others with those whose lengths we've indicated.
Watch out: the lengths of nails, both hand wrought and cut, may indeed vary from these examples depending on who made them, where the nail was produced, and its exact production method.
Below, Tremont illustrates cut nails from left to right:

Dating from 1590 in England, as the earliest report of nail production, the earliest reported cut nails in America are reported to have been cut, essentially by-hand, by Darrow in 1772 (Federal Writers Project 2013) with other authors crediting the Wilkinson brothers somewhat later, ca. 1783 (Benedict 1883).
The Wilkinson's realized that if the flat iron plate were simply shifted back and forth on an angle as each successive nail was cut from the blank, the nails would already be tapered and pointed, greatly speeding the process of making usable nails.
Nelson notes the first generation of cut nail manufacturing involved cutting all nails from common sides with heads hammered on as a separate production step.
The first nail making machines in North America appeared during the late 1700's - earlier than one might have guessed.
The slitting mill, introduced to England in 1590, simplified the production of nail rods, but the real first efforts to merchandise the nail-making process itself occurred between 1790 and 1820, initially in the United States and England, when various machines were invented to automate and speed up the process of making nails from bars of wrought iron.
These nails were known as cut nails or square nails because of their roughly rectangular cross section.
Cut nails were one of the important factors in the increase in balloon framing beginning in the 1830s and thus the decline of timber framing with wooden joints. (Kirby 1956)
Illustration above: a Read nail cutting machine. Nathan Read produced cut nails at their Salem Iron Factory beginning in 1798. Ezekiel Reed (un-related to Nathan) is credited with inventing the one-operation nail cutting machine in 1807. (Phillips 1993).
Jacob Perkins, inventor of a water-powered nail-cutting machine, began producing machine-made cut nails in 1794 and in 1795 received the first U.S. nail-cutting machine patent. His production combined an Ostrich nail cutting engine and a Vulcan nail-heading machine. (Phillips, 1993). The machinery skewed or "wiggled" the nail plate stock from side-to-side between cutting strokes, thus producting the tapered nail shanks that avoided having to hand-forge nail points or tapers.
Perkins' cut nails were formed to have a nail shank that is rectangular in cross setion with two tapering sides with burrs from the cutting blade appearing on diagonally-opposite edges. The nail head was flat, thin, irregular, and eccentric to the shank, and the nail shank just under the head was rounded and thinner than the rest of the shank - the effect of the vise that gripped the nail during the heading step. (Phillips, 1993).
A key contributions to nail production credited to Perkins was the production of nail plate stock that was sized big enough to permit cutting nails whose iron fibre or grain was longitudinal to the nail shank.
[B]ut in order to provide for this quality, also, in my said cut nails, when it is intended to make cut nails that is required to be clenched, I have the iron or other metal rolled into plates as wide as they can conveniently be made, and then have these plates slit or divided transversely into strips or plates, and the nails cut from these strips or plates will have their strata or fibres of the metal disposed longitudinally or lengthwise of the nails, which will render them as flex- ible as those which are wrought from nail rods, and equally susceptible of being clenched. (Phillips, 1993 citing English Patent No. 3365, application dated July 26, 1810; specifications filed January 26, 1811.)
Shown below are nails used to secure accordion lath - a plaster base found in a rural U.S. post-and-beam home in Wyoming County, New York.

Below: our green arrow points to the characteristic edge ridge that illustrates a machine made cut-nail.
The red arrow points to a split in the cut nail, characteristic of the effort to align the fibres of iron running down the length of the nail - discussed in our description of nails made after 1830 - below. .
These photos of antique cut-nails were provided by an InspectApedia.com reader June 2018.
As I mentioned about a different nail in photos on this page, the fact that the delaminating or split in this nail run lengthwise (parallel to the nail shank) suggest that the nail was of iron whose fibers ran lengthwise, making the nail one probably made after the late 1830s.
For these nails, because it appears that the two cutting/stamping burrs appear on the same side of the nail suggest the nail may have been made after 1840.
Below: Jacob Perkins' 1795 Nail Production Machine Patent. Perkins was a polymath described as an inventor, mechanical engineer, and physicist [Wikipedia] who held 12 American patents and another nineteen English patents. His machine for cutting and heading nails was issued when Perkins was just 24 years old. His nail factory was powered by water from the Powwow river in Amesbury Massachusetts.
Though still used for historical renovations, and for heavy-duty applications, such as attaching boards to masonry walls, cut nails are much less common today than wire nails. - source: https://en.wikipedia.org/wiki/Nail_(fastener) retrieved 2018/06/15
The cut-nail process was patented in America by Jacob Perkins in 1795 and in England by Joseph Dyer, who set up machinery in Birmingham. The process was designed to cut nails from sheets of iron, while making sure that the fibres of the iron ran down the nails.
Also see Pitt (2003) cited below.
Jacob Perkins' NAILING MACHINE PATENT No X-92 [PDF] was granted Jan. 16, 1795, to Jacob Perkins, Newburyport, MA, witnessed by Sam Coates and Edward W. Shoemaker. Regrettably all of the drawings are missing from the patent scan. Here we reproduce the photographic copy of Perkins' nail machine patent; the photo itself was made from the original on 3 March 1911.
Note: the first U.S. patent was issued in 1790, and in 1795 the U.S. issued just 12 patents.

According to “The WPA Guide to Connecticut: The Constitution State”, By the Federal Writers Project.
The first cut nails produced in America were produced by Edmund Darrow in 1722. It says:
“Early industry did not attain any importance until 1772 when a Bean Hill blacksmith, Edmund Darrow, produced from barrel hooping the first cut nails in America”.

There is another reference: “Reminiscences of Bean Hill, Norwich” page 297, written in 1897 by Burrell W. Hyde that states the same thing.
- play.google.com/books/reader?id=Wv8aAAAAYAAJ&hl=en&pg=GBS.PA297
Your website states that the first cut nails were made in 1790 (18 years later than 1772).
Can you tell me who is correct? I’m doing a research project and am wondering which reference is correct.
Thanks very much. - 2020/06/04
Thanks for the discussion, Bob. I think that for clarity we should distinguish between actual production of "cut nails" that included manual cutting of nails out of existing sheet iron (like a barrell hoop), and nail making machines that in turn could produce large volumes of nails.
My favorite source, often cited, for the history of nail making is Nelson, but the article above and also the references at the end of this page cite several sources.
Above, from Nelson, we note that nail making machinery dates back to 1590 - in England.
The slitting mill, introduced to England in 1590, simplified the production of nail rods, but the real first efforts to merchandise the nail-making process itself occurred between 1790 and 1820, initially in the United States and England, when various machines were invented to automate and speed up the process of making nails from bars of wrought iron.
To get back to your original comment, citing
We have on page 279 this by the author:
The author was discussing, in history of Sutton MA, the "Old Sutton Tavern", (an engraving is shown in the book) and writes about hand wrought nails used in construction of the tavern:
"As will be seen by the engraving, that represents it as it originally appeared, the siding consists of thick oak planks nailed perpendicularly to the frame, and at each of the upper corners the planing is placed diagonally, for the purpose of giving additional strenth in bracing the building.
The clapboards were not added until a later period. They were cloven by hand and fastened by hand-made nails, * cut nails being then unknown.
* About the time of the close of the revolutionary war two brothers of the name Wilkinson, who had ironw orks in Cumberland, R.I., cut a lot of nails from some old barrel hoops, "Spanish hoops," as they were called, and these are supposed to have been the first cut nails ever made.
The first cut nails produced in America were produced by Edmund Darrow in 1772. (Federal Writers' Project 2013) cited by you
Excerpt: “Early industry did not attain any importance until 1772 when a Bean Hill blacksmith, Edmund Darrow, produced from barrel hooping the first cut nails in America”.
And a similar but less explicit date crediting the Wilkinson brothers in Cumberland R.I., ca 1783 (as the American revolutionary war is dated as April 19, 1775 - September 3, 1783) - (Benedict 1878)
Benedict was writing a bit under 100 years after the end of the revolutionary war so was closer in time to the event of interest, but on the other hand the very recent (2013) Federal Writers' project may benefit from more extensively-available resources.
In sum I'd like to duck the trouble of who made the first cut nails by describing the history as
Dating from 1590 in England, as the earliest report of nail production, the earliest reported cut nails in America are reported to have been cut, essentially by-hand, by Darrow in 1772 (Federal Writers Project 2013) with other authors crediting the Wilkinson brothers somewhat later, ca. 1783 (Benedict 1883).

[This volume collects together the papers delivered at the first annual conference of the Construction History Society, held in Queens' College, Cambridge in 2014. Papers cover a wide range of topics all on the common theme of the history of construction, from the ancient world to the present day.]
The volume includes discussion of American cut nails and also of the British cut clasp nail, beginning on p. 233
In the illustration above those offset-headed nails were referred to by the author as spur-headed nails. Other sources (Nelson, NPS) identify these heads as used on sprigs and brads (finish nails) while the larger T-headed nails and rose-headed nails were used in framing and also in smaller form for holding wood lath onto framing as a plaster base.
With some justification, the Americans claim that machine production of cut nails was an American invention. From a simple beginning, the lever-operated guillotine machine patented by the prolific Jacob Perkins in 1795 was developed by various independent inventors into a series of efficient cut nail fabrication devices. [21]
By 1810 water powered nail machines had been developed, although American nail making predominantly relied on manual machines.
Nails of a primitive sort could always be cut manually by a blacksmith from heated barrel hoop or other strip iron and several instances of this resort to basics are recorded in the 1788 colony at Botany Bay. [22]
Perkins' later machine took the process one step further and cut tapering shanks from a heated iron ribbon. In order to maintain a taper to the proto shank, the ribbon either had to be wiggled through a shallow horizontal arc or flipped over between each cut.
Perkins' machine was entirely manual, but recent research has shown that at "black heat" of around 500 degC, the shear force of a typical nail shank drops to roughly 300 kilograms. Using leverage. this is easily attainable. [23] The device significantly speeded uip the cutting of basic nail shanks.
These simple headless brads have been found in Britain both of iron and steel, and were usually used in flooring or specialist work. (Fig. 3, nail 1). In American they would be re-heated and headed separately with either conventional facetted heads or bulbous oval heads would be formed with a hand-held die. ...

Above, adapted from Nelson (NPS), we summarize some observations that can help separate early cut nails from later cut nails used in North America.
If your cut nail is irregular in shank width and has the "A" type side burrs, it's likely to have been made before the late 1830s.
Even most reproduction nails that simulate hand-wrought fasteners will show regularity: the same simulated-hand-hammered head will appear on every nail, and you may observe the straight--edged raised rib of die cut nails made by machine.
Below is a modern cut nail showing the uniformly convex head on both sides of the nail head. This is the head of a modern machine-made cut nail.
Tremont Nail Company continues to manufacture reproduction nails which in appearance are quite like those made by hand more than 100 years ago.
The original factory was established by Issac and Jared Pratt in 1819 on the site of an old cotton mill which had been shelled and burned by the British in the War of 1812.
Known originally as Parker Mills Nail Company, it later became known as the Tremont Nail Company. - Tremont Nail, http://www.tremontnail.com/about.htm
Above is a "hand wrought style" machine made cut nail, produced by Tremont.
Shown at left is Tremont's standard Clout Nail: Similar in design to Shingle Nails, but made from lighter gauge steel, this nail was (and is) used for the application of thin siding and paneling.
It was and is also used for furniture repair, cabinet work, batten doors and counter tops. (Photo courtesy Tremont Nail Company).
The Mansfield, Massachusetts Tremont Nail company's historical notes indicate that nails have been made (by hand) dating back to 300 B.C.
Tremont further explains that in North America, nails were made by hand, often as a winter activity.
Below, using a Tremont machine-made boat nail as an example we illustrate the sharp edge profile (below left) and the line left along the shank of the cut nail by the stamping machine (below right) that characterizes machine made "cut nails" appearing in widespread use as early as the 1830's in the Northeastern U.S. and appearing later in other locations.

Ben, Georgia's Jekyll Island has had European settlers on it, as I bet you know, since 1733,
and according to https://www.jekyllisland.com/history/island-history/, the island has had human occupants since 1500 B.C.:
The earliest known archaeological sites on Jekyll Island suggest that this island has been a destination for more than 3,500 years.
Finding those nice brass spikes in a board gives us a chance to guess at their use if you can describe more about the board itself - or attach some photos (one per comment); It'd be useful to look at the saw or tool marks on the lumber.
The spikes are uniform-tapered and may be hand-cut, probably from the early 1800s.

How
Those look like modern machine-made cut-nails; I note that the nail sides are straight-tapered, not rounded, and absent any marks of hand tooling.
If you look closely, under magnification, at a cut nail you can sometimes observe which sides of the nail bear a burr showing the direction of machine cutting.
That in turn will match up with the two different generations of machine-made cut nails described in NAIL AGE DETERMINATION KEY
The "scuff marks" under the head of a nail are usually left by the clamping device that holds the cut nail in place for a second machine step that presses a head onto the nail top. We see that detail more-clearly on round shanked "wire" nails.
Thanks for asking and for the photo.
On 2019-10-04 by How old is this nail and what info do u have?
How old are these nails and where would they have been created?
They were randomly holding up flower baskets in the ceiling of the outside porch of my 1970s house.
I can see a little bit of a dip on one long side and one short side but they are consistent all the way down,
And there are some other smaller consistent scuff marks maybe all the way around the top of the nail? So my guess is it’s from a machine?
On 2019-03-17 by (mod) antique clinched cut nails
Taylor
There is no chance that your bent-over clinched nails are 400+ years old.
The nail shank is regular and smooth, not hand wrought - these are cut nails.
The nails are bent-over suggesting that they were originally clinched - driven through wood and their ends bent over.
Clinched nails are chosen with a length longer than the thickness of the target wood: the clinched-nails are driven-through wood and then the exposed nail shank is hammered over flat against the other side of the wood surface.
Clinched nails were used both for decorative purposes and for great withdrawal strength.
But a clinched-nail that is also a cut nail will be older than about 1830-1840. So your nails are less than 200 years old, probably newer.
At NAILS, AGE & HISTORY and
again in at NAIL AGE DETERMINATION KEY you'll read that because older iron, before the early 1800's nails that were to be clinched would have been hand-wrought since otherwise the cross-diretion of iron fibers (in early cut nails) caused the bent nail end to break off.

The photo of the nail is not quite sharp enough to look for stamping or grinding marks found on newer nails such as Tremont's reproductions of antique cut nails.
But near the nail head in your first photo I see what could be the remains of a modern nail stamping machine mark.
Take a close look along the sharp edges of the sides of the nail for irregularities or hammer marks. Those would typically mark an older nail.
Of course when if a nail or spike is badly rusted some of those details can be hard to see.

On 2018-08-27 by Dennis - researching Justin Morgan historic location
I have been doing some research and digging at what I believe to be a historical location.
For the past ten years I have been looking for and at last found a location where Justin Morgan (1747 - 1798, Springfield MA) (founder of the Morgan Horse see ... settled when he came to Vermont.
The general location had always been known however the exact spot was never known.
According to all of my documentation the spot that I have found is the location however in order for me to get the State of Vermont to acknowledge this location with a historical marker they wanted more proof such as some type of physical proof.
In digging at the location we have found nails in three of the four corners of what we believe to be the small log cabin structure that Morgan and his family lived in.
Vermont claims that the nails are not good enough proof because we cannot prove that the nails were from the 1788 time period when Morgan moved to Vermont.
History records show that the small log cabin structure was already there when Morgan arrived.
Morgan himself never owned any land that he settled in Vermont and the cabin that he lived in was on land owned by Joseph Griswold. Griswold was one of the original settlers in Randolph Vermont in which he was given land as long as he settle it.
The connection between Griswold and Morgan comes from Massachusetts ties.
The reason I am emailing you is because I have the nails that we found at the Morgan location and I am wondering if those nails can be dated in some way to establish their age?
Would you be able to confirm the age of a nail? Is there any way? Please email me at denlore3@denlore.com if you think you can help.
On 2018-07-16 by (mod) - age of cut nails in antique coffee table
The photo is a little blurry in the nails quite rusted so it's hard to see details but in one of your pictures I can see enough of a very straightedge to think that that's a machine made cut nail.
You can see the history of those in the article NAIL AGE DETERINATION KEY (live link at end of this page)
Remember that when you're guessing at the age of a nail and therefore perhaps the wood item in which it was used, you have to consider the location geographically since in some areas such as North America nail making machines were available on the East Coast much sooner than farther west.

I have to beg the question by asking the country and city where the nail was found since the use of cut nails or machine made nails and their history is not uniform around the world.
Your nail looks like it is machine made - the top is very round with no hammer marks, and the sides show a ridging characteristic of stamped out cut nails rather than hand wrought (and older) nails.
In the U.K. such nails were used between about 1830 and 1900.
In the U.S. the use of machine nails spread from earliest on the east coast, westward over a later period.
