    I’ve carried two for about 3 or 4 years now – one in each pocket. The general day-to-day safety and confidence it lets me feel is worth much much more than the price tag. I don’t live in a good town and I don’t hang out with the best people so having one for each hand is what I chose to do. Plus I have experience and am very comfortable figuring, which makes these daggers fit that much more naturally with my needs and comforts.

    The only problem is that they’re small blades (3.22″ blade portion for the regular size, 2.2″ blade portion for the mini) so you’re gonna be totally outgunned, so to speak, by someone with a 5.5-6″ blade or bigger. I’m in Canada and we have gun laws so a handgun isn’t a super great idea, I’ve been chased by people with butcher knives and hunting knives tied to branches (makeshift spears/long slashing weapons), threatened to be “gutted” by probably lying homeless war vets in Toronto and I’ll tell you these probably won’t do a lot of good for you in those scenarios (especially butcher knives and the self defense knives homeless people usually carry).

    I absolutely recommend these, they’re a great answer to bats, batons, really any impact weapon if you can close the distance and especially if you can get into a grappling situation. They’re a good deterrent for multiple attackers because one “wrong” move from either of your hands and more than one of them could dead or at least out. They’re good for single attackers even if you’re an “easy target” or whatever, again because each of your hands can kill or lead to a kill with one or two good stabs and when somebody pulls out two knives on any hypothetical attacker that will be their instant thought, “the threat has doubled.” If you’re inclined on wilderness self-defense I believe they would be an excellent suit for that as well, with an attacking canidae their neck is guaranteed to be exposed and you have the perfect downwards strike angle, plus you could punch and grapple with the head and jaws (obviously the dangerous part to you).

    Again I very highly recommend these but if you can’t carry a pistol or even if you might not want to (close-quarters, idk) you really really should get a 6″+ traditional fixed blade. With just one or two socps you’re gonna have to put up a hell of a fight to get around a knife that big without your own. Honestly I carry a CRKT OC3 with a 6″ double edge blade and my plan if I ever get caught with just my socps against a 6″+ is just to have them stab me anywhere but the neck so they’re close enough for me to get into their neck.

    So yeah obviously not fun to think about so if you aren’t using these alongside a firearm I recommend at least a 5.5″+ blade or an extendo baton. The main point of these is to get you out of close-quarters range to better handle the situation (escape, attack/defend further etc) but against a much longer edged weapon (which I promise you way more people carry with them than you think) you’re gonna want a gun or at least an equally big knife.

    My CRKT OC3 is honestly very comfortable (except it’s using a Benchmade Infidel sheath instead of the shitty one it came with so that helps), I’m like 6’3 175 and I wear medium and large clothes and it pretty much doesn’t print at all except for some of my light summer shirts. So don’t be afraid to buy another knife to compliment this one, or however many of these you may decide to buy. Please believe me, you need real deterrence and you need real overall-capability even though these are some of the best civilian self defense knives I’ve seen or owned
