力金 Chikaragane Power Metal

What is Chikaragane in Japanese Katana terminology?

This refers to a piece of metal attached to reinforce the feet or roots of the Menuki (a type of ornament on the handle of a Japanese sword). Alternatively, it can also refer to a piece of metal attached to reinforce the inside of the Fuchigashira (the pommel and collar on the handle of a Japanese sword). This not only strengthens the structure of the sword but also adds to its aesthetic appeal.
