Incredible knife and safety holster IFFFF you change the straps
I love to snorkel, kayak, and do stand-up paddle boarding. Some lakes have lots of weeds. The ocean is full of kelp. Weeds can be full of broken fishing lines. This knife seems very well planned and heavy duty. I love the size, the weight, the line cutter, the sharper serrated part. The safety release on the holster is great. The single significant problem, is that the designer of this thing made the straps to work upside down, which is not very comfortable. A very easy, simple solution is to toss the straps that come with it and buy a couple of better made straps. The following fixed the problem for me: https://www.amazon.com/gp/product/B09T24YR58/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Bottom line: I highly recommend this product with a different set of straps that are designed correctly.

Great dive knife.
So I saw people complaining about the hook that keeps this thing in, and they totally fixed that. It's now a button more or less, and keeps the knife firmly attached until you need it. There were also complaints about not having something to keep the loose straps collected, but I ran it through the holes on the case and it's not a problem. The design of this thing is solid, and it's not terribly sharp, but it can cut your finger (I found out thinking it was dull after checking it the right way). Taking this thing scalloping, will update after. :)

Great knife. Sharp.
This knife is good quality. It has a very nice sheath that securely holds the blade. Good height and has straps included to attach.

Great dive knife! The knife was relatively inexpensive so I wasn't expecting much but from what I see it's a solid knife! Well made, solid, great case, sharp sharp sharp! Fits my hand perfectly & comfortably. Locks in the case easily but secure with a quick system to unlock and hand. I wouldn’t pay more for another product. I’ve had mine a few years now and it’s held up and still sharp as can be.

Good Knife, but short straps!
I like the knife. It’s sturdy. You can take it apart. Keeps its edge. I just wish the straps were long enough to put on my thigh. I’m not a big guy, so I figured I would be able to do that. Unfortunately I cannot. It’s a small issue, but overall, this knife holds its value.

Takes A Licking But Keeps On Ticking
I've had my 2 Promate knives for about 4 years. I sharpen and oil them once a year at the end of the Summer, which takes me about 10 minutes. They are constantly in salt water with me from May until September. They hold their edge and after these 4 years, they each have a tiny small amount of rust stains - barely even noticeable. They are workhorses and they are awesome.

Great Knife, Great Sheath, Worth it
This is an ideal knife for anyone close to oceanic recreation! I take it fishing, diving, boating, etc. With me all the time! It hasn't rusted a bit and when it needs a cleaning I can remove the blade and handle without a hassle for easy cleaning! It's sheath also holds it in quite tight, I haven't had it slip out a single time! Perfect purchase for anyone embracing life near the sea!
