That is a cool little blade and more useful than most would think!
Over the years I have owned about every design out there for skinning/cleaning but that design you have in your hand is my go to design for sure . I actually clean most of my hogs and deer these days with the blade on a Gerber Diesel multi tool. The Diesel has that exact same profile and I love it. If you ever wanted to let one like that go maybe in a little flat sheath I would be your guy. Glad you are back at it buddy!
