## Description

THESE QUALITY DIVE KNIVES COME WITH A 100% LIFETIME REPLACEMENT GUARANTEE - Stainless Steel spearfishing knife, easily attaches to your weight belt, your arm or leg with straps provided. - Quickly and humanely kill your catch with this ideal tool for the job. Prevent the panicking fish from alerting nearby sharks to the feeding opportunity, keeping you safe. - By quickly killing the fish you will prevent lactic acids building in the flesh during the struggle, improving eating qualities. The fish will also redirect blood supply to vital organs away from flesh. - Bleeding and gutting the fish with this knife immediately after killing will also improve eating quality of your catch. - Rinse the knife in fresh water after use and return to sheath to store. This will prolong the life of your knife, helping prevent corrosion.

Review: Great dive knife - This is a great cheap option for spear fishing. I use it to brain the fish and gut before leaving the ocean. Durability is not the best as it will rust but for the price cant beat it. The sheath holds it strong and never had it fall out.
Review: Great little spear fishing knife - Welp I finally lost my knife - no fault of the knife, I set it down after I took it off my belt and left it on the beach somewhere… I bought this blade for spearfishing and it did everything it was supposed to. Stiletto point is great for dispatching. Steel take an edge well. I’ve brained, bled and gutted a decent number of small and medium fish now and never had issue… in a pinch the serrations actually work well to de scale and we’ve even filleted a few snapper and jacks with this little guy. The lock up is foolproof as well. All that and it’s cheap. Good disposable knife. I recommend 2 if you like how it fits in hand (because everyone says you will inevitably lose your dive knife and now I can attest that’s true). The coating seems to work. The edge itself will rust in salt water so remember to try and rinse/dry after use… I’ve only ever dealt with surface rust which is easy to buff out. It’s not the most ergonomic but that’s because it’s thin which I like. And it still works well in hand and is easy to use.

## Features

- 3.5 Inch long, 420SS, double edged blade, serrated on one side.
- Sharp tip for easy penetration.
- Comfortable handle.
- Knife sheath with clip-in style retaining system.

### ⭐⭐⭐⭐⭐ Great little spear fishing knife

### ⭐⭐⭐⭐ A- to A product (might be A+ after I get a few fish to test it out)
*by J***Z on August 23, 2016*

Update: After a season of spearfishing, and at the beginning of the second season I feel this knife is really great for spearfishing medium sized fish. The retention system is top notch and haven't lost a blade yet (previous dive knifes either came out too easily / lost or a PIA to get to release when I need it). I really like this after being in the water. I would definitely buy again. ======================================================================================= Westcoast Straighthookers is top notch seller, and worked with me very quickly when first package was lost by USPS. Initial impressions is that this is a 4 star product. It felt a little on the light side for sturdiness, but this is a highly specialized knife. What this is not: - I would not use this for heavy duty cutting (likely could get thru lobster trap rope on occasion but not up to the task all the time). - NO prying (blade too thin, and tang only goes halfway into the handle) What this knife is: -Smallish, Very Light (wouldn't even notice this on your belt) -Great sheath (Belt loop or leg straps) -Very good locking mechanism to hold knife in sheath -Definitely sturdy for shankin things (Tested on 2x4's out in the garage. Stabbed quite hard and seemed sturdy for that task). -Plastic in general is very good and seems to be non-brittle which is a very good thing -Very sharp tip that would do as this knife is designed to do (i.e. dispatch fish quickly). -Would require very little force to enter a fish, and easily controllable compared to larger dive knifes that are for general diving use. In general expect a surgeon's scalpel instead of a machete. Its a specialized tool that I think only a spear fisherman would want to carry vs. a normal diver. Its more like an ice pick than a cutting tool, but can do some light cutting jobs. I'll update my review this weekend if i'm lucky enough to get some fish.
