Knife idenity

[shigawire4sure]

Hello. Curious if anyone can help identify this blade? I picked it up here, not sure how long ago. Maybe 10 or more years. I recall it being from the maker and it being 52100. If very nice, I've used it a bunch and has always served me well. The mark appears to "B". Any help appreciated.
