I currently use the Ocean Master (Beta-titanium alloy which is their own formulaton) fixed blade diving knife and their folder. I have carred their folder for the past year due to the weight and rust resistence. Prior, I carried the POLICE model from Spyderco and Benchmade's AFCK (full size) for the past 11 years.

The good:

Sharp, rust proof, can be opened while wearing gloves, easily sharpened with carbide sharpener (sold at Home Depot for 4.99), light weight, thumb studs located on both sides of the blade, textured thumb rest on the back of the blade for increased thrusting, plastic grip is secure and "feels right". Plastic used seems sturdy.

The BAD:

Blade can be easily chipped if used to pry. I use mine as a staple remover and the blade marred (easily fixed with sharpener), clip is non reversable, action was initailly very tight (needed to be worked in and oiled),

Wish it was a liner lock. That would have been perfect.

Overall, I am happy with it.
