Scuba Choice Diving Low Volume Blunt Tip BCD Knife, Blue – Compact Safety Knife for Scuba Diving & Snorkeling – 2-3/4" Stainless Steel Blade

5 stars, big bang for the buck. Used exculively on ocean kayak fishing trips. Size is optimal in that it could easily be fastened upside to PFD, enabling quick and ubobstrusive access. Securely locks in place with its botton feature. Has not yet unintendedly fallen out of place, knock on wood. The case is made of hard plastic which initially, thought it might be cheesey, however, this perception became positive after regular use. The blade was comes blunted which adds a level of safety that a sharp tip does not have. I think this is advantageous on a kayak. In terms of corrosion, this has been used on four outings already and it was used for cutting dummycords (550 cord), fish, etc, and it shows no rust on the stainless steel. But then again, allout equiment receives a rinsing of water after each trip out to ocean. This blade also gets a generous spraying of WD40 w silicone to protect the blade. This knife is exactly like the Cressi diver knife but at a lower price. Also bought the Cressi and these two are exactly identical in every way, minus eched name.

I'd have given it a 5 if it were a rubber sheath. My knife is 304 stainless (better stainless qualities for salt water than 440c but is "soft" so not a good day-to-day knife). It is very sturdy and there is a small grey slide on the sheath (can see it in the pictures) that, with a push towards the tip, literally locks the knife into its sheath. I bought the knife for use on a life jacket (open ocean sailing) and I have no fears of losing this knife or that it might rust. This knife is non-magnetic (austenetic stainless).

The clip is worthless. There is no way to use the clip to make a secure attachment. I even tried zip ties and other diy attachment. And even if you could, the mechanism to unlatch and remove the knife from the sheath requires leverage and something firm to brace against. It requires two hands to open and I'm better off just leaving it in my bcd pocket. The low pressure inflate hose attachment option is more secure and will work one handed however it's a pain to deal with because it requires 4 tiny screws to attach. You could just leave the sheath attached to the hose. That could work for some people but when I travel, my regulator goes in my carry-on which means no knife. I'd have to pack it in checked bag without the sheath. It's just going to live in a pocket instead until it gets lost or I forget to pull it out for a good rinse and it turns to rust. Too bad because it's an otherwise decent little blade made with 304 steel and a blunt tip. All for under $15. For the price, I'm tempted to buy a second one just for the extra sheath but that seems silly.

It is unbelievably hard to get this blade out of the sheath . It is really a safety concern should you have to cut a rope or anything in an emergency. For the sake of safely, bc knife has created a larger safety issue.

Junk of a knife. Poor grade of Stainless. Rusts Immediately even afer immediately Rincing off the Salt Water.

Lost it on the 2nd dive of my Wreck training.The clip that comes with the sheath is not worth using, I should have used the hose mount.Use the hose mount if not storing in a pocket.Great value, cut thru webbing and monofilament.Ordering another one

Works well for snorkeling.

nice knife, though do keep in mind it is missing the tip. I thought they sold me a busted blade at first, but that's the way it's made. It's fine for me because I sometimes encounter flathead screws at my job. I use this in case my blade falls from insane heights. Though I wish the locking mechanism felt a little more solid, I do have to remember it was meant for diving, not climbing.
