Nice Little Knife

By Unknown Customer on 19 Jan. 2015

Being new to the diving scene I thought I should get a dive knife just in case. It's simple and affective. Only had to use it once, to cut a fishing line that had hooked my buddy, worked great. Only issue I have is that putting it back in can be a bit fiddly at times but isn't too hard after a little practice.

Perfect BCD Dive Knife

By William Chambers on 21 Apr. 2016

Perfect size dive knife for a BCD or just as a backup knife. Very sharp but with a curved tip, to avoid accidental equipment damage. Supplied with a really useful webbing sheath but it also fits perfectly in an old Northern Diver KN166 hard sheath that I had in my diving spares box. So I was pleasantly surprised to have stumbled on a very cheap replacement KN166 knife. Happy diver.. Thanks Guys.
