Antique & Reproduction Nail Identification Key

On this page we illustrate and help identify cut nails of various types. The use of nails and their features are also factors in guessing their age.

What is a "Cut Nail"?

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.

Is it a Cut Nail & How Old Is It?

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.

First Nail Making Machines in North America - 1790 "Cut Nails"

1772 - 1820: In North America early machine cut nails

Reed Nail Cutting Machine in 1798 (C) InspectApedia.com adapted from Bradlee cited in these articlesDating 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.)

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.

Who made the first cut nails in America?

An inspectapedia reader asked:

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”.

- books.google.com/books?id=E07pCAAAQBAJ&pg=PT324&lpg=PT324&dq=Edmund+Darrow+1772&source=bl&ots=D6v851C38P&sig=ACfU3U3CziUWfa8g5zLnoFOeE62bQF-oWg&hl=en&sa=X&ved=2ahUKEwiuz6yx4-bpAhWQT98KHYZEBIwQ6AEwAHoECAYQAQ#v=onepage&q&f=false

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. Bob Dees 2020/06/04

Moderator reply:

Machine made cut nails used to nail accordion lath in a New York home (C) InspectApedia.com PrestonThanks 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.

Old Sutton Tavern in Sutton MA, (Benedict 1878) at InspectApedia.comSo we have

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).

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.

American cut nails

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. ...

Modern Reproductions of Antique Hand-Wrought Nails

Cut nail differences before and after late 1830s - adapted from Nelson, NPS - at InspectApedia.com

[Click to enlarge any image]

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

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.
