Dive Knife Suggestions...?

[loki]

CRKT ABC Hammond might suit you, functional, and won't break the bank. Another great brand is Myerchin they make an offshore safety knife I think the model is MYA500. Spyderco has the aqua salt in a fixed and folder. It's made of H1 steel so no rust but it is a little more pricey than the others. If it is going to be for work I would go for the Myerchin or the Spyderco, if it is just recreational or hobby the CRKT should suit you well. I found a link with all of the said knives are on one page.
