This impressive bladed implement the Victor Lee VL-03B Fantasy Folding Knife. It features three 3″ curved black stainless steel blades that can fold into the knife body. The handle is anodized aluminum and has a belt clip. It kind of reminds me of the Glaive, minus two blades, of course; based on some reviews I’ve read I also wouldn’t suggest throwing it.
You can get it off Amazon.
