Blak Ti Worker, Need Info.

[Hoosierdaddy]

The gun store that has the Blue Centofante also has what appears to be a Blak Ti Worker (C01 BK) Unfortunatly no box. So it's hard to tell if it's original. The knife coating looks sprayed on, if you close the blade you can see where it didn't cover the entire blade. Inside the scales you can see blue and purple colors from heat, just like when something is case hardened. The blade steel is G-2 (Gin 1) so I believe it is old. The Spyderco Catalog list this model as new in 92. They have it for 99.95, but again no box <img src="sad.gif" width=15 height=15 align=middle border=0> Any one have info?
