Rated 5 out of 5

Flat head

Good quality with a secure sheath fit and sharp edge. However you do want to keep it coated in a think silicone grease layer for corrosion prevention if you ocean dive.

Great performing knife

Knife is well made, very sharp and balanced forward of the blade which is what I wanted. As always primary benefit of this knife is the locking mechanism which I can hear click when under water for positive feedback of proper sheathing.
