A dive knife is not used for fighting off the monsters of the deep. This knife is designed for use as a safety item to cut through lines and nets that you could get caught up in whist underwater. I bought this knife as a replacement for a much larger knife which i felt was cumbersome and unnessesary.
This knife is primarily designed for mounting onto a buoyancy control device (BCD - this is the jacket you inflate with air to give yourself neutral buoyancy so that you don't sink or rise when unnderwater), This is an ideal location to secure a dive knife as it easily accessible when you get stuck and your arms are not particularly free. I much prefer this to the other dive knives I have wich are either strapped around your leg or put into a pocket meaning fumbling about to get it out.
The suppied mounting system took a bit of working out but clips onto and oceanic BCD easily once it is figured out. Unfortunatley it wonlt clip onto all makes of BCD so you need to check it is compatible before buying. The sheath does have plastic loops at the side so straps could be attaached easily to secure the knife to your leg. Straps are not supplied but normally cost two to three pounds each.
The kife is secured in a solid plastic sheath which has a locking mechanism and quick release button. It slots easily into place and you can feel a firm click when it is locked in position. The release button is simple to operate and easy to use when wearing thick gloves in cold water.
The blade is blunted at the end, making it harder to hurt yourself. Personally I think all dive knifes should be blunted as the point doesn't serve a purpose and is only really there to make you feel like some sort of commando. The blade has a serated and smooth cutting area which means you have the option of sawing through thicker obstacles or cutting fine ones.
It s quite a small knife with a blade of 66mm, but this is more than fit for purpose. Weighing about 85g means it is lightweight and less cumbersome than other knifes.
There is a line cutter (the little grrove in the blade) which makes cutting thin lines easy.
A metal butt on the handle of the knife is a nice feature which allows the knife to be used for signalling by banging the butt on your metal cylinder. This makes a loud sound that can be heard underwater but the direction of sound can be hard to identify (I find a strobe better for signalling).
The build quality is good. The plastic is well formed and the locking mechnism works extremely easily.
The blade is made from 304 stainless steel which has better saltwater resistance than some stainless steels but it should be protected out of the water using a silicon grease or some vaseline as a cheaper more available option.
The knife is extremely sharp. the manufacturer claims 'razor sharp' but I think i'd struggle to shave using it.
Priced at about £20 this is a very resonably priced knife as the mounting kit to the BCD is included. The materials are good quality and the knife is easy to use. Highly recommended, although it looses a star due to incompatibilty for mounting to non-oceanic BCDs.
