I've not taken this exact design, but some that are similar. Let's be honest here...we're not reinventing the wheel. There are designs that work well for different people for different reasons. I can say to some degree that I designed this knife....but if you look hard enough, you'll likely find something very close to it. So it boils down to the details. I like this design (style) because it works in all positions. It's not the safest design around, but I'm not worried about that for myself. The functionality is great....it just comes at the cost of safety. I wouldn't give this design to a kid for his first knife, but it's what I'll be taking with me. Hope that helps.
