Blood grove?

I can't be the only one here who remembers "Dark OP's Knives". They were the height of mall-ninjery and SPECOPS fantasy some years back. With their ridiculous designs, high prices, and over-the-top ad copy they were a running joke for several years here at Bladeforums.

To give you an example of how they advertised their knives, they had descriptions like- "blood grooves to re-direct blood spray when de-animating Taliban fighters". I kid you not, they actually said that stuff, and more.

I checked, and it looks like they went out of business. Not a shock, and no loss to the knife world (although a loss to the world of comedy).

Anyway, just thought I'd take that stroll down memory lane and maybe provide a chuckle. Whenever I hear "blood groove" I think of Dark OP's, and "de-animating" 😁 .

🤣😂 Dark OPs. Those were the silliest knives I ever saw. Thanks for the laugh…I had happily forgotten about that “brand.”

IIRC weren’t there all sorts of uncomfortable looking points and hotspots littering their models?

Shame on me for not providing a pic.

Mmm, mmm, that's some good de-animation 😁 .

I use the fuller on my Chevalier as much as the flipper, it's very much functional as a one-handed opener too!

I meant marketing by calling it a fuller instead of a long pull, not that it is useless. Traditionally that would be called a long pull I mean, not a fuller.
 
I don't know, it sounds like those Dark Ops guys really know a thing or two about the operator lifestyle...

"The edge bevel is an extreme, nearly razor edge 70 degrees. Can be used as both a thrusting and slashing close-in, defensive weapon. The serrated top edge offers a much broader edge radius, and is designed for hard use cutting and hacking, preserving the razor edge of the main blade. The back taper of the broadening penetrator tip is beveled as not to catch on bone or clothing when withdrawn from the wound. "

I bet you could shave all day long after deanimating your enemies with that 35 degree per side edge too!
 
Fullers have existed for centuries on larger blades such as swords. On smaller blades, it wasn't used much until the late 19th century. Then again most knives didn't have the 1/4" thick blades that todays designs have and a fuller was not only not needed but pretty much impossible. When Webster Marble used a fuller on his Ideal model, it started to catch on and soon enough every blade, large or small, had to have one or it just wasn't right. If you wanted to sell knives in the American market it had to have a fuller....
FYI, according to Webster Marble, the fuller on the Ideal made it easier to sharpen in the field btw....

The best reason for a fuller on a bayonet is because when you attach it to a rifle, the weight on the end of your bang stick changes the barrel balance for the shooter. I don't know how many other places did this, but we would occasionally do live fire shoots with bayonets on, just so soldiers would get a feel for the difference.
 
It's a blood groove and you can't change my mind. I know for a fact that when I stab someone and remove the knife, it will cause copious extra amounts of blood to flow. Enough blood for 3 Tarantino movies.

Fullers go back a long way. A functional one is used to reduce the weight of a sword, large knife, bayonet etc... without significantly compromising durability. It uses the same principle of an I beam in construction work to reduce weight and resist bending or excessive flexing.

If the old designs replicated in "Forged in Fire" are an indication, a lot of old designs used them to reduce weight. I'm sure the old makers decided that a real thin blade wasn't strong enough, and a thicker blade got to be too heavy. (And the judges on the show frequently comment that some of the blades in the competition are too heavy.) So somebody decided that grooves could remove some of the weight.

Ding ding, it took 16 posts, but someone said I-beam! Take a drink everyone and let's close the thread! 🤣

Please lets not get derailed into that conversation.

No, no you have it all wrong. It's not so there will be more bleeding but so that your knife doesn't get stuck due to suction! All high speed low drag types know that!

Also I assume extrema ratio is still in business. Since dork ops basically ripped off some of their designs if some of you want them you can get a dork ops terrorist deanimator still... Or something close to it.
 
Fullers are great for lightening blades which is very important in balancing larger blades folder’s not so much but still cool. The blood nonsense is just that

Errg! What I really need is a fully serrated Microtech Jagdkommando!
 
Blood grooves are very bad. So bad it should be forbiden. When one stabs another the pressure from the body splashes large amounts of blood thru that groove. Very easy to spot the stabber. That's why assassins use saber ground or flat ground. Even hollow grind can help the extreme splatter. Don't you guys watch those Japanese films when there is a cut the ceiling gets red from blood. That's real, you know!!!
