Cons: None

What you see is what you get.

Got this as a back up blade and have been carrying it on my belt for a couple days now. I barely even notice it and have already forgotten it was there a couple times. Compact, lightweight and razor sharp and built like a steel shithouse, I'm even optimistic for once in my life that I won't break something. I plan on giving the blade a paracord wrap to make it perfect. Thanx goes to Knife Center for their speedy shipping and great selections! 💪

perfect

I think this is the best steel for a knife like this. I make my own sheaths because I have never seen a good sheath on knife priced like this or any price range for the way I carry it. You need to make a sheath to fit your requirements. One size does not fit all. This is for concealed carry when you want a knife and not a gun.

Drop forged boot knife

Well made with no blemish found. very solid but not too heavy, razor sharp. Both sides the same slightly hollow ground flats totally symmetrical. Sheath is outstanding with clip that locks like a vise grip. I wiped the edges with sentry marine toughcloth. This is a fine example of the cutlery art.

Some decisions are easy

I have a philosophy- a single edged knife is a tool and a double edged knife is a weapon. As a long time collector and father of 2 active duty soldiers, I buy this kind of knife with the knowledge that one day, one of my son’s lives may depend on it so here’s the deal…. this knife is the real deal. Before I send a knife to one of my boys I wail the crap out of it. This knife is sharp and durable - exactly what I expected from Cold Steel. I rated this one a 5 but it’s really a 4.5. It’s gray, not black. The handle should be skeletonized to reduce the weight and take a paracord wrap and the sheath design with the UltiClip is just ok. This knife is big for a boot knife so the sheath ought to integrate a horizontal carry option into its design. Carrying a tool vertically attached to a belt is perfectly acceptable. Carrying a knife as a weapon should be stealthy because the element of surprise may just save a life.

Great knife!

I bought this knife for my dad who is currently serving overseas. Cold steel has given me a great first impression, the knife arrived fast and the finish and edge sharpness was perfect.

Forged steel boot knife

Excellent! Came out of the box shaving sharp. Perfect size for a boot knife. I had my doubts about how it would handle, but these were rapidly dispelled.

Strong knife

Top knife for the money. Razor Sharp out of the box. I bought 2 for testing. I abuse them a lot but the knives stay Sharp only the finish worn of.

flake

Good quality for the price. wish it was black or satin finish. gold is too much bling. Guess I should not have used it like a work knife.

Good drop forge

Great shape and size. Came very sharp and slices really well. The blade finish on the silver/grey knives is very smooth, however it does wear off fairly easily. Underneath that finish it has another finish which is black and considerably more durable. To me this is the only reason for a 4 rating instead of 5. Otherwise the knife is excellent for the cost. I have one of each in the series and may duplicate some. Kydex sheath is excellent for horizontal carry.

Excellent dagger but the defective sheath makes it useless

Everything about this knife is good except that the sheath is defective; it does not hold the knife in securely enough. If I shake it a little bit holding it upside down it falls out. I have several knives that use this kind of sheath, including a few made by the same manufacturer, so I know how they should work. This sheath has four little lugs on the sheath that should fit over the handguard but do not, and that defect is why it doesn't hold the knife securely. This defect makes the knife worthless, because if it is ever used in self defense, or in any survival situation, that's a time that there can be sudden and forceful movement, so it's the time the knife is most likely to fall out, and if it falls out in a situation like that it could be fatal for the one carrying it. There is no time that would be good for it to fall out, but it is most likely to fall out at the worst possible time. I sent Cold Steel's fake Customer Service department two emails explaining this problem to them and asking them to send me a sheath that is not defective, and both of them were totally ignored; no response at all. My guess is they made a lot of them defective and just don't want to spend the money to replace any defective ones. But whatever their reason is for ignoring this problem, it makes this knife useless, because I will not carry a knife that might fall out of the sheath. Other than that it's a good design and excellent knife. The following review is what I would say if it was not defective: Daggers are typically made to be sold, not used. But this one is made to be what a dagger was designed to be, and used the way a dagger is meant to be used. This makes it a good backup weapon for those who can legally carry lethal force. Given current technology it is not possible to have a knife that holds a good edge, is not brittle, and is stain resistant. The best material for a knife blade is steel; anything mixed with the steel to make it stain resistant makes it either brittle, and therefore prone to breaking under hard use, or soft enough that it doesn't hold a good edge. This knife, as with many Cold Steel knives, is made out of pure steel. There are good stainless steel blades, if you want to spend the money on them, but even the best stainless is inferior to pure steel when it comes to a good combination of toughness and edge-holding ability, and this applies especially to a dagger. The downside is that pure steel can rust. But remember that men carried and used knives long before stainless was even available. Vikings carried knives, swords, and axes made out of pure steel in open boats over salt water, which is very corrosive, and their weapons served them just fine. Just learn how to take care of it. Pure steel also seems to be relatively inexpensive, so this really good knife (and others like it) doesn't cost much, relative to the inferior stainless blades. The sheath is also a very good feature. I put a couple of grommets in heavy duty suspenders and lashed mine to one of them upside down. It's out of the way, secure, concealable, and very accessible. But there are many possibilities, depending on how you dress.
