The Deerslayer and Sharpfinger are two different models. The knife that you have is the Deerslayer, not the Sharpfinger.
You are correct of course. Due to blade similarities I always called it my Sharpfinger, sort of like an "Extra Large Espada," and wrote it as such. I see it referred to a lot as a Sharpfinger Deerslayer.
I'm trying to find out more about it, esp. what steel it is. I've seen it as 1095 on the BigStore but don't believe it. It has a pretty high polish to it. Bought it '72 or so...another long-time goto knife I took for granted til today.
I probably should start a separate thread....
