I have one of those too. And yep makes a helluva spear. But not so great as a knife/tool. All metal, no comfort when chopping, slippery in the hand. WOrth having for sure but if I'm only taking ONE knife I'd have to look again at the Glock. Heck I own one but I need to get it out and look at it some more any way. I may need two or three of them.
i wrapped para cord on my handle for grip. Also gives me around 10 or 12' if needed. I think a guy on YouTube dipped his handle in tooldripdip from Home Depot and I liked that idea too
