Should you visit a history museum in Japan, and, like I do, make an immediate beeline for the collections of samurai armor and weaponry, you might be surprised to notice that Japanese swords are customarily displayed with the stitching removed from the hilt. Visually, it sort of dampens the impact, since the remaining skinny slab of metal is a lot less evocative of it actually being gripped and wielded by one of Japan’s warriors of ages past.
The reason this is done, though, is because many Japanese swordsmiths would “sign” their works by etching their names into the metal of the hilt. Some craftsmen achieved almost legendary status, becoming folk heroes whose names are widely known even today.
The most respected of all, though, was Masamune, whose reluctance to sign his blades has made identifying them difficult. But difficult and impossible are two different things, and for the first time in over a century, a sword has been confirmed by historians as being the creation of the master himself.
