The Sharpfinger style is, or has been, made by several companies. A great all round utility piece, also great for concealed defence carry if legal where you are. In fact, if someone called it 'tactical' Sharpfinger, it would no doubt sell for twice the price.
My stainless Camillius has quite a blocky handle and every edge, I don't mean the blade, is sharply squared off.
My carbon Schrade 502SC by contrast, has a lovely 'melted' finish, like a bar of soap, the sort of thing gunsmiths do to handguns to make them more user friendly.
So, the cheap Chinese one is fine for knockabout utility but it's such a great design that it's worth seeking out other variants. As previously stated, it's still cheap and easy to do on ebay but I suspect not for much longer.
Both of mine were made in U.S.A.
