鑿 Nomi Wiki
Posted: Fri Jun 26, 2015 12:50 pm
There are many types of Japanese chisels, nomi, and a number of different ways this section might be organized. I've decided to proceed mostly from the common to the unusual.
First off, a drawing giving the terms for the various parts of a chisel:

-------
追い入れ鑿 oi-ire nomi, lit. 'drive in chisel'. A variant pronunciation is ou-iri-nomi. Also known as 大入れ鑿, ō-ire-nomi, meaning 'big entry chisel'. Also known as zō-saku nomi, 造作鑿, zō-saku meaning 'house fixtures'
This is the most common form of Japanese chisel. A general purpose mid-size bench chisel for woodworkers. Can be used by carpenters and carvers alike. Typical length is 22~23 cm. Blade widths range from 5輪 (5 rin, about 1.5mm) up to 3寸 (3 sun, about 90mm). Often sold as a 10-set, in which the standard sizes are as follows:
3mm, 6mm, 9mm, 12mm, 15mm, 18mm, 24mm, 30mm, 36mm, 42mm.
A typical example:
The head of the chisel has chamfered upper arrises, a form termed kaku-men-tori, (角面取り), often abbreviated men-tori. That's the most common form of chisel head:
There are other head shapes.
If the chisel head form does not have beveled arrises, but a form with a non-chamfered upper section called kaku-uchi oi-ire, 角打ち追入れ. It was the common chisel head shape before WWII.
Here's an example:
総角打ち, sōkaku uchi. Where an entire set of chisels has the kaku-uchi head shape, as in the above picture. Sometimes, the larger chisels in a set will have the men-tori shape of head to reduce the heft a little, which does end up looking a bit like a mis-matched set..
If the head of the chisel has a triangular cross section, then it is termed a shinogi oi-ire nomi, 鎬追入れ鑿. Here's an example:
Shinogi-oi-ire-nimi are also called umeki-oi-ire nomi, 埋木追入れ鑿, the term umeki referring to inlaid plugs or patches fitted to conceal defects and such.
