This knife DESIGN has the right idea. All you do is push the button and it releases the knife. The problem arises when you actually do it. The plastic holding in the knife is too long and is exactly ninety degrees. Thats a problem because you can't release the blade with one hand. In order to get it right you'll have to do some precision filing in almost no space to move a file. Also, the straps are rubber. In theory this is good for a dive knife, except for when its cheap rubber. I've had this knife for less than a month and the rubber is seperating from where I only adjusted the straps. Also, if you dive in a shorty suit, then the rubber will grab ALL of the hair on your leg if you wear it on your calf. Which you will have to, because if you have big thighs (and if your a dude who dives you probably don't have small thighs) you can't strap it anywhere but you calf.
