Yes, but I'm not a fan. There is no real reason why. I have a couple of plexiglass ones as well as a typical flesher with the single handle for fox, marten, rats, mink, fisher etc.and the fancy two handled type for beaver/wolf.
Guys like them a lot. I just have a preference for what I already have. If I needed a fleshing tool, I would look at them. They don't wear out or break.I have never heard of anyone sharpening one so I cannot comment on that.
The checkering on the handlers do fill with fat but all handles gets greasy. It isn't a problem.
