In what direction do you sharpen your knife for self defense?

I didn't exactly intend to make this thread silly. I am aware having a knife is not the best choice for a self defense weapon, otherwise I wouldn't carry my glock 22 or my sr40.

I made this thread in regards to cutting performance revolving around the directions you sharpen a knife and how they may effect cutting performance in a self defense situation. Perhaps the knife is a back up because you are unable to draw your firearm for whatever reason.
 
I use silicon carbide paper on a granite tile.
So I guess I normally sharpen it sideways.
I just sharpen it till it's sharp.
Then when it gets dull, I sharpen it again. :)

Don't overthink it too much.
Sharpen it for utility (test it out on the things you will actually cut in daily life), and, in the extremely unlikely event you need it for defense, it will cut in that situation just fine too. :thumbup:

As for "experts", some like serrated.
Some like plain edge.
 
.....A dead body in an alley, with multiple stab wounds, slashes, and a line of blood finding its way down the gutter. The detective, gloves on, finds a cellphone, the numbers '91-' on the screen. Under the victim's body he finds a black bladed, assist open supertactical model ****, and examines the blade. Moments later he mutters "of course!". "What is it, sir?" his assistant trainee asks. "Look here," he says, holding the blade so the edge bevel glints in the haloed glow of the streetlight; "the victim's edge directional scratching left a less than optimal cutting surface, barely wounding his assailant, and allowing him to escape.".... The assistant looks up at the detective and asks "You're bullshitting me, right?" "Yes, old chum, I am; he might have run, his phone almost had '911' on it, and besides, 'Bladeforums' dispelled that myth some time back. Call crime scene, and let's go get a donut." The assistant looks one more time at the bloody body, and mutters to himself "bad place, bad decisions, bad awareness, bad luck.".....

I hate to even respond, but its almost like the difference between punching with the first two knuckles, or the bottom three. If you have a hand on them all your punches hit harder. If you use any sort of trap on the limb you're cutting, it won't really matter what edge finish you use - the additional support pressure from the other hand will have a serious multiplying effect on the cut in excess of other conditions as long as the edge is in good shape. Stabbing doesn't care what grind direction. As I was introduced to it, most cutting occurs on a retraction, stabbing on an extension, rake the grind pattern down toward the hand to take marginal advantage of this tendency.
 
My apologies to the few here that get it. I am disgusted at the immaturity and ignorance that plagues these forums.
 
In self defense it matters little; its where you deliver the cut or puncture that counts and the force behind the strike, not how the edge was sharpened. When I was training at black belt level, in my early sixties I could drive my hand, fingers first, completely through a large watermelon. Its well known that the human hand has no sharp edges the same thinking applies to any object used as a weapon. A set of car keys, a comb, a rolled up news paper or a ball point pen all make good self defense weapons; no sharp needed.

I for one appreciate the levity :)
 
If I ever own knives for self defense in the future I would do swirls, figure 8's, loops, +'s, X's, etc while sharpening to create a truely random scratch pattern to make random micro serrations which is bound to make it more difficult to heal. The way I figure it will be slightly harder to cut on a microscopic level, but the body won't get practice in healing a consistent cut like you do if your blade is like ///// or \\\\\\. When it's truely random it won't get used to it and will take longer to heal, after all practice makes perfect. Why won't our bodies be the same when it comes to healing :rolleyes:.

Though for self defense I tend to use a Forget-Me-Stick, I highly recommend it. You can take it off of your local minion near you, and should you fail you won't remember the ordeal :D.

How doe's that work out for you? I tried using the kitchen sink but it wasn't too EDC friendly and when you have to go uphill in the snow both ways to the next nearest working kitchen sink it get's old quick.

I also tried using a large metal alarm clock and put a chain on it so I could swing it around like a flail and it double as a necklace when not in use for self defense or keeping time. But people kept calling me Flavor Flav, so that was short lived.
