Bought one of these to use when doing beach and pier cleanup dives. I had a really large blunt tip knife that I decided to retire. When cutting lots of fishing line, snips are the best, but these make short work of any underwater chore. Nice deep serrations are great on rope, and the blunt tip is much more handy when prying, poking, and anchoring yourself in the sand. Safer too, as you are far less likely to accidentally stick yourself or your BC. You can insert the blade from either side into the sheath, which is a quick squeeze to remove. As a bonus, this knife fits perfectly in the XS Scuba neoprene sheath. The only drawback is that it is stainless, not titanium, so make sure to wash off the saltwater and give it a good coating of silicone. I left it in its sheath and soaked it but it still rusted a little. You need to soak it separately and open.
