Got these from a buddy I know a little about them supposed to be works of art the blades are signed.

Hi Honestmike,

The blades are called Kogatana and the handles are called Kozuka. Most were signed and as usual quality goes from dire to absolute miniature works of art.
Some of the Kozuka were signed on the rear as well.

The second Kozuka down looks interesting, Is it made of iron ?

Regards

Yes it is, They all are signed or marked I try to put bigger pics and it just doesn't work out.
