As it is I rely on Home Depot for a lot of things related to dive gear but this takes the cake. I was there today looking for knife related stuff and just walking through the isles my eyes rested on this in the duct tape section.
It's marketed as a serrated duct knife. Hardened stainless steel. Blade is 14cm, handle is 12.5cm, overall length 27cm. The blade is pretty stiff, I think I could chip rock with it. The handle is nice and grippy, the back has a stainless steel piece that can be used to hammer. The sheath is nylon webbing and has one loop in the back to put on a belt. $12 :0
It's a little big but over all a very good tool for the money. I bought it just to take some pics and show you guys and was going to return it but now I think I'll keep it.
