BladesUSA MD-1BS Diving Knife 9-Inch Overall,Black

Great for bush craft hunting Spears

Nice knife for the money

With over 35 years of dive experience, I had a Dacor Techno (slightly smaller) version of this knife costing $130. I lost it on a dive when a strap broke. The price of this knife is insane. For its size, and stability in your hand, you won’t find a better bargain. Although it’s not the same thickness, weight or sheath quality of the aforementioned knife; it is still an exceptional value. I could lose a dozen of these knives and still have money in the bank. 4 star because the plastic sheath and rubber straps could be better. That said, this is an exceptional find.****************************************************Titanium dive knives are most often titanium oxide coated steal because full titanium dive knives are extremely expensive. Frankly put, I personally don’t find the expense of those any real value. The moment they get scratched, they corrode where the scratches are and/or underneath the titanium oxide.For dive knife preservation, I find a little silicone gasket grease or O-ring grease along the blade edge and the locking punch of the knife work’s extremely well. As with all dive gear, proper cleaning goes a long way with preservation and durability of your gear. A simple rinse with fresh water then towel dry and reapplication of silicone O-ring grease along the blade edge and locking punch (or any scratches) is all I do prior to my dives and/or storage. Remember not to overdo it since a little goes a long way. The reason for multiple purchases are dive buddies either lose their expensive knives or swipe mine. Also, tool handle silicone dip is also great for the handle of these knives without compromising the use of the sheath. You can find the “tool handle dip” or silicone dip on Amazon or at any hardware store for a couple bucks.****************************************************REPAIRING YOUR RUSTED KNIFE:Let your knife soak in white vinegar for a few hours or in Cola or *Ketchup (works really well) until the rust is gone. You can use a soft brush to spot-treat really bad areas. Make sure it’s a natural fiber or soft nylon brush (old toothbrush preferred) since any type of metal brush will damage the knife. Rinse with fresh water, towel dry and apply silicone as described above.

Let's be real here...this is a cheap $4 knife that I got on sale. If you don't expect much you won't be disappointed. However, with a little work this is a decent utility knife. I didn't say dive knife, I said utility knife. Remember we're only talking 4 bucks here. You could use it as a dive knife, but it would disposable at best. Salt water will ruin this knife super fast.Stainless Steel? Yeah, well sort of. It's probably the lowest grade of stainless as a strong magnet will pick it up. Expect this knife to rust in any adverse condition. Keep it clean and dry and it will suffice. Salt water is a big no-no.The rubber straps are narrow and very long. I saved the straps for a different project. Never throw away decent rubber straps as they always come in handy for something else.The sheath is hard plastic and very clunky. I tossed it. I have some extra sheaths that will accommodate a 4" blade.The knife itself is decent. I like the serrations on the opposite side as I don't lose any blade length. The thumb rise and quillons are the same. The tangs has holes to lighten up the overall length and provide attachment points as needed.The blade is 4.25 inches with a rather crude bevel. About 5 minutes on a stone sharpened it right up. If you have a small diameter sharpening stick you can touch up the serrations as well.The handle/tang seems to be made for paracord or a rubberized coating. I scuffed the tang with 600 grit wet/dry paper and wiper her down with acetone. I dipped the handle 4 times using plasti-dip.A little time in the shop and this knife is well worth 4 bucks.

Se oxida un poco, y es muy incomodo pero por el precio funciona bien.

I ordered this knife for my husband bc the locking mechanism had broken on the sheath on the other one. Now he walks around the house with this knife strapped to his arm (for no apparent reason). 😂🤣😂 Needless to say, I think he loves it!

I work around boats for a living. Very often I need to cut ropes or other such marine objects. This little knife is perfect for a quick fix. I have it fixed on my right boot and it works very well.

I use this in the sea and works good and for the price it is amazing but it gets little rust stains in different places
