It's a French fisherman's knife. Pearwood handle, unique proprietary blade locking ring, been around for century or more. Cheap. Like $10 for a #8. I've had the #12 for a couple decades.....I can't wear it out. They are the best darn cheap knife I've ever found. When I say beat the crap out of it, I mean just that. I use it to split kindling with a hand sledge, pry bar, screwdriver, you name it, I do it. Couple licks on a stone puts a razor edge on it and it holds. You use one of these and then understand the damn stainless Rockwell uber hard blades are just a pain in the ass. They're kind of a cult blade. When you see someone else with one you both look at each other and smile. They make a really nice mushroom knife and a couple other specialty blades. Check it out....
