lets say, for example, you are paddling in an area where there are lots of crab traps. what would you do if you went over and got tangled in a trap line? cut the line with your knife.mewisemagic said:Being a newbie, do I even need one? When would I use it?
Sorry to change the topic.
I would recommend against this. The main reason being that cheap knifes tend to rust quickly. As a dive instructor, I carried a knife on my vest (blade up) for around 2000 dives. I never came close to losing it, even when in some pretty rough conditions. If you go with a quality knife, it should stay in the holder without you having to worry about it. Any local dive shop should have a good selection of knives, but beware, a lot of the cheaper ones will rust if you are using them around salt water.jurgenk said:As Daren mentions they do have their uses and I would advise to buy a cheap one as (especially if you have it on your PFD blade up) it is possible to lose one (I have) and you do not want your $60 knife going for a free dive.
