Ok, this is pretty much the only dive knife you'll get on Amazon and not cry about losing it on the first day of use if you do of course. It's a nice dive knife, case is plastic and does have a push with one hand operation. The straps feel good around my lower leg. Who cares if it lasts. Nothing in salt water lasts anyways so to buy an expensive one would mean you got money to blow or your lacking something else. Lol It could save your life so the cost goes well with the construction of it. I'm using it for a basic Lobster dive snorkeling. Hey don't forget to get a dive light too for those under rocks see! Get one that has the 4 AA. Ok I'm out! Be safe!!! Reply and I'll tell you which mind blowing dive light I got that is awesome! Oh by the way I got the sharp point in green. If you drop it you can spot it quickly in dark waters. It has happened to me so many times I keep buying knives so like I said nothing lasts forever!
