Yes I found it an interesting Tanto. never seen this style of koshirae. The F&K are part of the tsuka=carved wood, not applied parts. same with saya, the koiguchi Kurigata & kojiri are all carved wood. at some point in time, someone slopped a lot of lacquer all over and it does have some worm damage. but the blade is nice,and has a fine habaki IMHO
