Very handy little knife, I use it as a "Kill Knife". Since Im just starting to spearfish, I havent mastered kill shots yet so as I bring my fish up to my kayak which I dive with,...the knife hangs over the side so I can quickly (Grab & Stab), then I toss my fish in a cooler on back. I know my method might sound a little strange but I lost the sheath since it didnt come with straps and this actually works better while im trying to handle a wriggling fighting fish. Im giving it 3 stars cause its cheep , very sharp and nice and handy,...I actually even filleted a Hog Fish with it too! It does rust pretty quickly so maybe Ill upgrade for the next one.

Reviewer: Charlie Floyd  -  View all my reviews
I have not yet had a chance to get this knife in the water either salt or fresh. However I have tried to learn the proper method of removing the knife from the sheath. I have a similar knife be another manufacturer but with a blunt tip. I find the removal of this new knife from the sheath to be a tad more difficult than that of the knife I already owned. Perhaps this is not all bad as the knife will certainly stay in the sheath.

Rating: Sharp, Sharp, Sharp, and SHARP!
Reviewer: LOUIS D.  -  View all my reviews
This knife is no joke. It is razor sharp and I learned that the hard way. I was too lazy to get up and get a pair of scissors, so I instead decided to use the knife, which was nearby. The knife immediately cut through what I was cutting and cut into the top portion of my thumb right to the bone between the two knuckles. Needless to say, I have a pretty nasty looking scar thanks to this knife, my laziness, and stupidity. The sheath is sturdy and locks the knife securely in place. This is a good knife and the price is dirt cheap.

Reviewer: Marcus Yoder
got this for my son(13) for christmas. felt like he was old enough now, and as he is getting more adventurous, he might find himself in pickle where he needs a knife. i took the good advice of another reviewer, as he explained that ... well, if you it while out in the water its likely not coming back. the price point to quality reviews made me feel like this was a good purchase.

Rating: fits nicely in pocket
Reviewer: ruth lyons
like I said, it fits nicely in pocket....but forgot it was there and did not take out after a few dives....and it rusted in spots.I just cleaned it up and oiled it, but I am suggesting that others thoroughly dry after dives.Great price!

Rating: Great knife and terrific price!
Reviewer: Norma L.  -  View all my reviews
I love this knife. It is good quality and the perfect size. The only reason I gave it four stars instead of five is because of the website advertising printed on the knife but that is the only reason for the inexpensive price. You are receiving a good product for a great price in exchange for a little company promotion.

Rating: Great knife for the money
Reviewer: Michael H.  -  View all my reviews
Saw this on sale for cheap and thought what the heck I could always buy another one when it breaks. Turns out it is a pretty good knife for what we paid for it. Complements my wifes Hera BCD very well.

  • ruth:

    which knife makes more sense for a beginner?

    Bill  (Certified Scuba Instructor at

    The sharp has a notch that is used as a line cutter and is a good choice.

  • ruth:

    which knife makes more sense for beginners?

    Darrick  (Certified Scuba Instructor at

    Hello Ruth, any knife you go with will work for you very well. I would suggest going with a blunt tip and go with titanium. It will not rust like some of the stainless steel knife.

    Hello Jacinta, yes there is a bracket on the back side of the knife sheath to attach to a 2" weight belt webbing.

  • Shannon:

    Will this knife/case float if lost in the water?

    Darrick  (Certified Scuba Instructor at

    Hello Shannon, not the will not float in the water if it comes unattached. It would sink to the bottom.

The handle features a finger and thumb rest giving a comfortable and secure grip even when wearing gloves and a solid metal butt cap designed to allow the diver to make more than enough noise to attract the attention of the divers around him or her.
