An Inside Look at Handle Geometry
A rare opportunity to compare the inside and outside geometry of a finished handle core. Historically an old tsuka would be split open for repair or adjustment or even re-purposing for a new blade, however a newly crafted tsuka is always glued together before the outside is shaped. In this unusual case the core was…

Eyes on the Spine: say No to the kink, and Yes to the flow
One of the most common mistakes when attempting to recreate a Japanese classical style tanto is to caricature or over exaggerate certain design elements while entirely missing others. The Japanese aesthetic is subtle and nuanced, millimeter differences can make or break the lines of a blade or koshirae. A subtle curve is almost always more…

The omote is the “public side” of a tanto or sword, the side that faces outwards both when being worn and when on display. The edge faces upwards and the…

The tang and handle of a classical tanto are constructed in a manner that requires only a single bamboo peg to hold the entire knife assembly together. In addition to the sense of beautiful simplicity, this design allows the knife to be taken apart for cleaning, polishing, or sharpening work. Carving and fitting the inside…

Classical Tanto Geometry: Nakago & Machi
The geometry of the nakago (tang) is very important as the assembly of the knife hinges on the correct form and construction of the tang. Viewed from the spine, the thickest part of the blade is at the machi (notches) and there is a distal taper towards the tip of the blade and towards the…
