Morihei Hisamoto mirror finished stainless clad ginsanko stainless ai deba. Ai deba are slightly narrower and lighter than the standard deba, halfway between a regular deba and a mioroshi deba. 

Excellent finish grinding and polish on this hand forged ginsanko, ginsanko is stainless but has a lot of the characteristics of carbon steel as far as edge formation and cutting feel goes, ginsanko is essentially shirogami with enough chromium added to make it stainless.
