Not having a life and lots of time, my brain drifted over to the topic of deploying your knife under stress. Did a bit of Internet reading on the subject. Gave it some thought after Bugs Bunny was over. The old ones. New cartoons stink.

But I figgered, doesn't really need to be in a physical altercation, but maybe an accident, or house fire. Making a shelter if you get lost. Someone with a bad cut on their leg. Something like that.

I know from past experience and training that under stress, one of the first things that gets lost is ones fine motor skills. I would think the more experienced trainers would agree. When the adrenaline dumps, using smaller items in your hands and with your fingers can be problematic. Even manipulating your handgun gets tough.

I would think that in a stressful situation where your knife is needed, it should be as easy as possible to hang onto with wet hands, such as water, oil, blood maybe, etc. You should be able to open the knife while wearing gloves. And you may need to open it with your off hand. So it needs to be off hand friendly.

I've knives with about every opening method out there so I was kind of able to experiment a bit in a completely unscientific comparison. I'm not going to get into locking mechanisms because, for the most part, any knife lock used will suffice just fine for the average guy out there I think. Providing it is well made and not a cheapo gas station liner lock just waiting to close on your fingers. In a situation, your knife may be put into awkward angles and blade pressures, so you want to have confidence in your preferred lock. What is the best lock out there has been debated forever and will never be agreed upon. Same with opening methods.

Anyway, I wanted to keep the knives right around the same size, so I used a plain small Sebenza with double lugs, Native 5 G10, Emerson Mini A-100 with thumb disc - no wave, Benchmade Mini Bone Collector with hole, and a Benchmade small Ritter with thumb studs.

That gave me a frame lock, back lock, liner lock, axis lock. Thumb studs of different sizes, thumb disc, thumb hole. I left out the wave opener method. Mostly cause I don't like it myself. Lol. Some guys love it. And I think once you get it commited to muscle memory, it'd be ok. I always ended up half opening the knife in my pocket.

My tasks were pretty simple. Cut up some cardboard. Cut a few couple foot lengths off a coil of 3/4" hemp rope, whittle some shavings off a two by four for kindling, and cut down the length of a pant leg to get to what's underneath. A board in this case since my wife wouldn't volunteer. She wouldn't donate any blood either.

I used water, 10W30 motor oil, spray canola oil, and mud. Made a heckuva mess on my knives, but I cleaned them between each test. I didn't dunk the knives either. Just kinda flicked the stuff onto the handles and the blades. In a real situation, you may have to fish your knife out if a mudhole or something. Who knows. I did hit each knife on my Sharpmaker too after each deal.

I went bare handed, surgical gloves, and those cheapie brown gloves you can buy in packs since I didn't want to ruin good winter gloves.

I'm not going to bore you with each step as this post is too long as it is, so I'll just say how it went for me. YMMV widely with certainty.

Bare handed, all the knives were easy enough strong handed. After I ran my hand under cold water for awhile, then dried it, but while my hand was still real cold, the Sebenza was a little bit of a struggle. Those tapered, on the small side thumb studs, for me, were difficult. When oily, my thumb kept wanting to slide off with the detent of the knife a bit in the heavy side maybe.

Bare handed off hand, the Native, Bone Collector, Emerson, the Ritter, then the CRK, in that order, I found easiest to open. While the Sebenza is a very well crafted knife, even double lugged, it just isn't too off hand friendly since the frame lock design prevents a larger "dip" to get your thumb onto the stud. And the tapered studs I found harder to use, especially with real cold hands. The thumb disc, and the larger studs on the Ritter, coupled with the lighter detent found with the axis lock is noticeable.

I found as I proceeded thru my tasks, the knives stayed pretty much in that order of effectiveness. For me.

I'll have to admit, while I'm find of my Sebenza knives, it was tough to use during the oily parts with surgical gloves or the brown gas station gloves after I glopped some oil on the knife or sprayed it with canola. It was just really slick and hard to do anything with much force, without it wanting to slide out off your grip. Cussed at it a couple times. And I think you would have to admit, by comparison to the other knives, except maybe the A-100, the handle is fairly small and thin. The Emerson is thicker though.

After it was all said and done, I came to the conclusion, strictly speaking for me, the most versatile and easiest to use knife for those different tasks with those conditions in place was the Native, then the Bone Collector. Both with Spydie Holes. Both with nice grippy handles on the larger side.

With the lightweight brown gloves, or the surgical gloves, when the knife is oily and wet, that Sebenza was tough for me to work with. I think with bigger, heavier, winter gloves, the CRK, and the Emerson, maybe the Ritter, would be tough.

Whichever knife you want to use, and think maybe you may come upon an urgent situation without other tools once in your life, you need a grippy type surface, such as G10, access to the opener from either side with or without gloves. And be able to complete basic tasks with either hand. Obviously your off hand won't be as good for some tasks and I did have to struggle with some things a bit more with my off hand and it took me longer. And the handle needs to be shaped well, and large enough, to provide a nice grip.

I intentionally left out closing the knife as I figured that's something you can do later. I did kinda tap a few times on the board with the spine of each knife just to see if any would slip, which they didn't. I didn't do spany goofy batoning or really smacking them. While I was messing around, I did purposely move the knife into odd angles and stuff while working with them. Like pulling the knife back out while applying upward spine pressure. All knife blade locks took that in stride.

Please, please, keep in mind, these are all knives I own. Many others as well. I picked these as they are all similar in quality I think, and very common in use among knife folks. I mean no disrespect towards anyone's favorite knife or locking method. This is just something I did messing around for my own amusement. I didn't record it. No referees were in place, nothing scientific by any means. And I have a total zero in any kind of knife fighting training or skills. Speaking for myself - if I get down to where I have to use my knife in a fight, I'm likely well and truly fu@cked. Feet don't fail me now. Lol. But it could happen I suppose. Never say never. Especially in these times we live in.

So for me, a Native G10, with its nice big cutouts for the thumbhole on both sides, reversible clip for lefties, is a nice daily carry knife choice that I have confidence in that I could use most effectively in less than ideal situations. Will I always carry it from now on? No. Too many other knives I like too.

Also, these steps were very relaxed. Nobody was screaming. Well, I did once when I cut myself. Wasn't on fire. Wasn't dark. No blood other than mine. Wasn't in an unfamiliar area. Wasn't real cold out. Wasn't pouring rain. Wasn't being rushed. Wasn't in danger. So if I were to add one or more of those factors, it'd suck all the way around. Lol.

So glean what you will, and I would just suggest maybe taking your favorite EDC, and trying a few different tasks under less that ideal conditions and see what's what. You could be surprised. I was.

Very sorry for the very long winded rambling thread. And I hope I caught most the typos. :)

I have to agree with you and the ease of opening the Spydie hole. I can easily open most of them even with heavy winter gloves. In the winter, especially when I will be outside in cold weather or when I don't want to take off my gloves, I almost exclusively carry blades with a deployment hole. I find that thumb studs are nest to useless with heavy gloves. I have found that some of the Spydie holes are sharper than others on the edge and this also helps me when wearing gloves.
 
I agree with you and I have noticed a bit more than that.

You didn't include a flipper, I would be interested in how one of those would compare in your tests. I'm not a flipper fan like some people are but I am carrying a ZT 0561 this week and it is relatively easy to open. It takes a second to position my finger in the right spot and the blade has a very strong detent which requires a strong pull, but otherwise it is fairly positive to open.

I have a lot of knives with thumb studs and a lot with thumb holes, and the one flipper. I have noticed that a lot of knives with thumb studs take careful deliberate action to open and even then it is not positive. The thumb studs are hard for my thumb to hit because they don't stick out very far and sometimes the scales don't have relief cuts to let you get to them. The tops of the thumb studs are rounded or tapered or whatever and it is hard to get traction. Frequently my thumb will slide off without opening the knife. The one exception to this is my Kershaw Blur. The end of the thumb stud is very sharp and it is easy to get enough traction to open it.

Now as for blade holes- one of my first modern folders was a Benchmade mini-AFCK. It works well enough but the hole is a bit small and the edges of the hole are rounded a lot so it is hard to get traction. Now I have a lot of knives with the real thumb holes like the Paramilitary 2, Manix 2 and Military. The big holes combined with relatively sharp edges that give a lot of traction make these knives the most positive to open in adverse conditions. I have a Spyderco Bradley folder with slightly smaller thumb hole and that makes it a bit harder to open. My Delica for me is much harder to open due to its small hole.

Except for the Kershaw Blur which ranks pretty high in this regards, my Paramilitary 2 and Manix 2 are the easiest and most positive of my knives to open.
 
Bdmicarta - yeah, thought of a flipper, but not being a fan, I only have one. A Kizer frame lock in all Ti, so I didn't use it.

I did wonder though if it'd still flip gunked up with mud or something. Although I'm assuming it'd at least start open, then you could finish opening with the studs.

I was a little surprised that the frame and liner locked worked ok, but as I mentioned, I didn't fully dunk them in the mud either. If you did, I'm guessing you'd need to knock some of the crap out first. But I'm not sure.
 
The thing that I've experienced as an EMT (once to the detriment of my index finger) is that it's very, very easy to get focused on the task you want to accomplish and forget to pay much attention to actually deploying the blade. Spydie hole with cobra hood is probably the best manual knife, but autos and A/O knives have their place for deployment in stressful situations, not because they're faster, but because they tend to be all or nothing. Either the blade doesn't come out, or it's locked in place and ready to go.
 
IMO the easiest knife to open/handle is the one you use almost everyday, and are most familiar with. I think a lot has to do with muscle memory especially when under stress and your fine motor skills are at a loss.
 
Do a search for the guy with the Manix 2 that saved his life! He had a tire thrown at his head in an attempted mugging. He deployed the Manix stabbed his attacker with it while partially blacking out. Great story! He had photos as well! It's the first real world evidence that I have seen of anyone using a knife on an attacker who wasn't a nutjob.
 
I want to add more about handle. The partial grip during opening requires good/stable purchase as it's held in place to overcome the retention.

I don't have many higher end G10, but comparing the Resilience, Endura and Bradley, the Endura with bidirectional texture wins! Strangely the Bradley with the CF is quite grippy though.
 
OP - Great post - thanks. I have similar concerns about ease and security (hanging onto the knife) of deployment under stress and possibly in motion (changing body position, even). I would agree with everything you said - round large holes work best for me, possibly because I have been regularly using spydercos for years. Thumbstuds are worst. Thumb discs - on my Emersons and ZT/Emersons work much better than studs and I'd rate those 2nd to the hole. I have (or had) a few flippers, including southard (still have it), domino (sold it), and ZT 562 (sold it). Flippers require a weaker grip to manipulate the "switch" while keeping fingers clear of blade. Wave works well on some knives but not others. I like the spyderco waves especially, and some Emersons. But I trust the spyderco holes. Even in winter with gloves on. I have Raynaud's and a lot of folders I can't open at all with my fingers when my hands get cold. It is fixed blade and hammer grip time then (or no knife at all to be safe). Anyway, opening holes get my vote.

Oh, and totally agree on gripiness of bidirectional frn! Delica is a great edc for that alone.

I think that the answer to the easiest, most reliable which also requires the least motor skills blade to deploy is, and will always be, a fixed blade.

However, this answer leads to another share of questions related to ease, convenience and legality of carrying it.

In my own experience, with cold numb hands there isn't any folder which I could trust my life to. I mean cold like in ICE CLIMBING BELOW ZERO WITH WET GLOVES AND HANDS ABOVE HEAD LEVEL FOR 15 MINUTES or cold like in WINTER DIVING. Often I am unable to manipulate climbing gear untill the blood warms up the hands again (which is painfull like you couldn't even believe), much less pull out a folder, open it and cut whatever needs to be cut. Chances are I will end up hacking at whatever needs to be cut with my ice axe if my life is in danger!:D

Edit to add:

Just to keep my post in line with the OP, I think that out of my Spydercos, my Military is the one with the biggest hole, and the one I usually carry when I expect to have gloves on.

Also, regarding flippers, I do have an old (like 16 years old) CRKT M16-14 with no LAWSK and the Carson Flipper. And now that I think of it, It might be the easiest one to open with gloves on, since I only need to push on the flipper and it opens by itself. The heavy blade helps. Too bad I don't like the blade shape and grind much!

I agree with the OP that the Sebenza is hard to open with the off hand due to the lack of propper cutout in the frame lock side.

Oh yeah, a fixed blade would be the way to go if you're knowingly entering into a crappy situation.

My thought was going for what most people normally have along with them in their day to day meanderings. Here in the U.S., I would think, and I could be wrong as I don't know the stats, it'd be a sub 4" folder of some type, often sub 3 1/2", depending on your local jurisdictions. Many folks just have a SAK or other type of slippie as their main blade. In NYC it seems about all you can have is a wooden tongue depresser. Lol. I know some folks do prefer a small fixed blade though for daily carry.

My alox Electrician will suffice just fine for 99.9% of the normal things I do. But I like to add a pocket clipped knife often. Just like them. :) The SAK would be hard tho' with very cold hands, or all mucked up.
 
My carry almost always consists of at least one Spyderco. Ease of operation is one of many reasons. Sorry you had to muck up your knives to sort that out. :p


I agree though, in a life and death situation the thumb hole may not be enough. I'd definitely like to be shooting for the hole over a stud. Like others have stated, that probably has a lot to do with familiarity too.
 
What about the Wave?


Joe58 That gave me a frame lock said:
The Wave may work well for those who like them. I've never cared for it much, so I usually have trouble with it. But for those used to it, I can see it may be good. I'd be curious if any members have tried the Wave opener with messy hands or a slimy knife.
 
Somehow I had a looooong post written and the damn browser didn't want to post it.

Anyway. I wanted to point out that yes, you can screw up and drop the knife while you attempt to pull it out and open it on the seam of your pocket at the same time if you don't have a decent grip on the handle. However, in the event of having numb fingers unable to grasp the blade, you can always snag the wave somehere and just pull to get it open.

I own a Delica and Rescue, both WAVED. I also carried a ghetto waved Endura (zip tie) for 9 months while working in Cairo. And a Victorinox Soldier as well! They do work for me, unless I am wearing flimsy pants...
 
I have knives with thumb studs, or other deployment methods, and I always stick with a SpyderHole! Old habits are hard to break.

I can testify to this. When my hands are impaired, as long as I can hold a handle at all I can get a waved blade open by snagging as described. This works one-handed. If my hands are at that point I can open a spyder-hole blade, but it takes two hands (no control over individual fingers).

I usually carry a small fixed blade too, but accessibility is often not as good as a clipped folder (the way I carry anyway), and still takes two hands - one on handle, the other on sheath. I rarely carry a fixed blade on belt (except IWB) because of snagging potential.
 
...still takes two hands - one on handle, the other on sheath...

I think this is fully depending on the kind of sheath you are using. Most of the leather sheaths require two hands because they rely on snaps and buttons for knife rettention. Most of the molded sheaths (Kydex, plastic or whatever) retain the knife without the use of any additional strap... so they can be pulled out with one hand only. I had the luck of getting during a knifemakers christmas exchange a beautiful small knife in a kydex sheath... and it is a joy to draw with only one hand! Falkniven plastick sheaths for the F1 and S1 also work this way.
 
I think that everyone should find the knife that they feel most comfortable with using on their weak side. I have given this much thought and found the the perfect (weak side carry) knife for me is the Delica 4. I can open and close it with my left hand and use it (or at least try as best I can) with this hand as much as possible, just in case I am unable to use my right side. I find my self working from ladders quite often so I never know when I may not be able to let go of something with my right hand. Now on the flip side of that there is always a paramilitary 2 in my right front pocket. So in my opinion you should always have a knife ready from either side. Because when an emergency happens you may only be able to react and if one practices for this it may save a life which could be your own.
