Review: Quality knife for a convenient price - This knife is such a great deal for the price. When pulling it out of its sheathe for the first time, i was impressed by the look and feel of the blade. The serrated edge, blade and line cutter were all very sharp right out of the box. Went on a dive last night and had no issues with it. No rust then next morning either. One thing to warn of is to keep it away from sand as much as possible, for if any gets in the button/lock mechanism, it can get jammed. Some sand got in mine and it took quite a while to clear it out. Overall one of the best dive knives to buy for the price.
Review: Great for the price - I looked for a while for a diving knife with a point that would be suitable on my calf/ankle. This had the best straps, the best buckles, solid snap in case and a high quality knife with serrations to cut through tough rope. It met all my requirements, and with a bit of whet stone it works quite well and stays in good working shape. One concern, which is fairly easy to remedy- the rubber straps will slip loose from the plastic buckles. I bought a couple of extra strap clips from a boating store for a couple bucks, and was able to adjust the perfect fit for both straps and secure them from being loose ends with the one extra add-on. That's the only reason it gets 4 stars instead of 5. There are few strap and buckle systems that are perfect, especially when you are considering water making certain materials contract, and that rubber has the least irritation in water with skin and hair. Oh, and the snap-in securing system for this knife works very well, I was concerned from photos but you can get the knife out and put it back into the sheath without looking after just a little practice. Well worth this price, would still be a good product for double.

### ⭐⭐⭐⭐⭐ Great Knife, Excellent Company!
*by C***E on July 16, 2013*

I ordered one of these to use on my multi-day kayak trips. I decided to go with a diver's knife cause I wanted something that would not instantly rust if it got wet, and I since I usually wear gym shorts in the kayak I needed something that I could strap to my leg instead of a belt. I just got back from my first trip with it on a river, so I can't attest to it's salt water use, but here is my experience with it... When I first got it and opened the box I noticed that one of the little tabs in the back that holds the blade in was broken. It was still usable, but since that piece was broken I decided to contact the seller to see if they could send a replacement part. They immediately sent me a whole new knife! A+ for customer service. I love the way the it has a fine edge on the entire front of the blade, and a serrated section on the back. The sheath is ABS plastic, not rubber as mentioned in a previous review. There is a spring clip on the knife that keeps it from sliding out of the sheath. I was worried that the rubber straps would cause irritation on bare skin, but it never did and it was perfectly comfortable to wear on my calf for 2 days (about 8hrs each day). So far I have only had to use it for cutting paracord, cutting the top off a bottle, etc. and it seems to do well for general use. Got it wet a couple times and no rust so far. Not much else to say about it other than it's just an all around great knife. The only con I can really think of is that the straps have a belt style lock system and not plastic clips like I thought from the picture, but I didn't see this as a real problem. I'm sure there are other better knives out there, but for the price you can't beat it!
