The First Modern American Scythe Nibs

Up until the mid 19th century, American scythes had used the English method of affixing their nibs: an iron loop was fastened to the shaft of the snath by means of a wedge driven between the loop and the snath itself. While this allowed the nibs to be positioned at will along the snath, the wedges were prone to working their way loose at inconvenient moments, and in the industrial boom of the mid-1800’s a number of innovations were made in the means of fastening nibs. The most notable of these is the method that eventually became the standard: the so-called “Clapp’s Patent” nib. Patented in 1838 by Joseph and Erasmus S. Clapp of Montague, Massachusetts, it was the first nib known to bear the form that we see so commonly today on almost all snaths, both new and vintage. The nibs made currently by Seymour Midwest Tools are effectively of the same fundamental design.

We were fortunate enough to come into possession of an original example of one of Clapp’s Patent nibs, as well as a contemporary clone by Lamson Co. This company was particularly notable, for its owner and founder, Silas Lamson, is commonly credited with having inventing the steam bent curved snath as we know it today. This innovation is often cited as having been in 1834, though we have documentation that places it as much as 6  years earlier.  An 1830 document declaring his letters patent include, among other innovations, “the mode of fastening the nibs without wedges” although we do not know the specific mechanism used. As can be seen in the following photos, our Lamson nib is nearly identical to the Clapp one. The Clapp patent seems to have been at the center of a court case regarding patent infringement in 1840.

Restoration: Seymour No.2 Bush Snath

A professionally restored Seymour No.2 bush snath outfitted with a new old stock Swedish-made Banko bush blade. The Seymour No.2, now long discontinued, was similar to the still-produced No.1 grass snath but with a thicker end diameter and a four-hole heel plate rather than three. The holes are arranged in a “♦” shape rather than the “▼” arrangement on the No.1. Some older examples of this snath have capped nibs, with a three-pronged, domed, circular brad having been driven into the top of the nib to cover the recessed nut and projecting thread of the nib iron.

A Traditional “Rag Knife”

A traditional style of farm knife made from a broken American scythe blade, usually used for topping root crops.

The blade below crack was cut back to the spine, which was forged out into a tang. Normally this would have been simply wrapped with rags to form the grip (which is why they were called rag knives) but we used a reshaped billhook handle instead.

The tang is peened on the end and the grip tightly wedged from the top inside the ferrule for an extremely tight and secure fit.

Vintage American Scythe–Offset Seymour Ironclad

A fully restored and tuned Seymour Ironclad swing socket snath outfitted with an Emerson & Stevens “Clipper” grain cradle blade adapted for haying use. The snath has been significantly shaved down, the nib blocks replaced with ones of improved fit (the upper one having been modified for proper interface) and new grips installed on the original nib irons. The hardware has been electrolytically de-rusted and thoroughly cleaned, the whole tool having been given a protective clear coating.

Finding The Balance

Establishing the actual balance point of asymmetric tools like scythes or axes can be fairly difficult, since the real point of balance often lies external to the body of the tool itself. The following shows a method using a plumb line, two suspension points, and photo overlays to approximate the location of the center of gravity.

Why bother with this, you ask? It depends on the tool. With scythes it can assist in adjusting the horizontal balance or determining the “power” of the unit relative to its overall weight, with axes it can help in determining an ideal head and handle pairing (of particular importance in axes with a minimal or totally absent poll, like the one shown here) and with both tools it can aid in establishing the proper hang of the blade/bit. The axis of rotational balance for an axe will lie along a line passing through both the grip point and the center of gravity.
