No more liner / frame locks for me !

Then why did he have it in a half grip? It had to be if it folded and cut his left index finger where it did. Why would a person have a knife with a well designed handle like that in a half grip? Could it be because they would want to apply more force to free a stuck blade? A half grip would give more leverage on the stuck blade and I'd bet he was twisting it as hard as he could, to try to get it free. These modern locks just don't fail so easy, unless you do something wrong.

yes what happened unfortunately is something like that , a second without attention , but I think the same thing would not happen to axis lock / triad lock , don't you think so ?


any way I think I will look for an edc fehrman 3" to 4" long blade
 
FWIW, I've seen more than one mention about the Tuff lock disengaging with light spine whacking.

I was reiterating what the OP said. No speculation on my part. Not trying to start an argument. As others have stated, we weren't there(well maybe you were, but I wasn't). When I was making feather sticks and accidentally disengaged a liner lock there was no twisting or sideways motion. I simply pulled back and the knife closed partially. Enough to scare me and make me take a closer look at how it happened. I agree with your theory that his hand was not gripping the entire length of the handle. As I said before, I shy away from these locks, meaning I don't buy new knives with this type lock. I do however own some. I am just more careful when using them nowadays. Also, to be fair I don't own a tuff.
 
Sucks to have a knife close on you. I would also suggest an Izula 2 or the like. I use this knife because it easily fits in my pocket and isn't too scary for other hikers. It goes with me to places that a large fixed won't. If you want to stick to a folder though, maybe try a friction folder like the Sword peasant knife(or custom for better steel). This way your hand holds the tang to the scales and the blade can't close unless you let go.

Not in the same manner, but if you had a axis lock and pulled back to free it out of stuck wood, I can see how you could pull the lock backwards. The traid locks are tough, I don't care for the knives they commonly are used with though. Like I said I don't fully trust any folder for just going at something the same way I would a fixed blade. To me they are for cutting, that is downward on the edge and emergency defensive use, at least that's why I carry them. Anything really hard I use my Blind Horse and I have used it just as you were the Tuff, with no damage to me, or the knife.
 
If ya play hard, eventually, you're gonna fall hard. I toy around with my knives all the time. I consider it practice and testing. I've taken down an oak pallet with only a Strider SnG. I was at a car camping party, everything was wet & collecting was illegal but someone brought pallets. For starters, I stomped & used a large rock to do the initial large to smaller pieces. I know I could have accomplished all tasks with rocks, but let's face it... it was knifey playtime! Everything from making tiny kindling to batoning varying pieces. It was the only cutting instrument I brought and I was the only one with any such tool! I treated it as if it may, at any moment, close on my fingers or even just break. When batoning a folder (rare for me and not out of necessity) I've done it with the blade unlocked so as to not muck up the lock interface. "Chopping" with a folder will almost definitely "peen" the stop pin, deform other interfaces, and likely cause other damage as well. So IMO that would only be a life or death option.

I would put more faith in a knife that is purposely made to be excellent, THEN priced, such as an SnG, over a knife whose manufacture is purposely chosen as a cheaper option (Taiwan). Then again any time I'm going out to play in the outdoors I typically bring a Fixed blade knife and a folding toy.
 
For years my dad used a Schrade LB-7 lock back to dress deer. He even cut through the pelvic bone with them. (he had two) He never had a failure of any kind. Not because the lock was so tough, but because he understood the design and worked with it so the force was on the blade's edge, not on spine, or tip. The lock was just there to help out, not take anything a person could dish out.
 
Sounds like a fixed blade is needed here. That looks like a pretty bad cut indeed. Hard to say what exactly went wrong, but If you are really crankning down on a folder, especially when it's stuck in something you need to use caution as well as a more appropriate tool.

Sage advice here.

I know you should use a knife properly and all that, but I don't want a knife closing that easily. For those of you did not open the link, the guy locks it open and hits the spine against his other hand's palm, and it closes. He does not hit it hard at all, and it is repeatable. I don't think if grabbed a large sampling of liner/framelock knives, you would get any others that will close like that, not that easily. I have seen the stupid spine whack tests, but that is concerning. This coming from a guy wanting to buy the Tuff, I think there may be an issue with that knife, not all liner/framelocks.

I wonder if they had some early models that were defective, and the newer ones are good to go now. Seems to be the case. This isn't the only Tuff I have heard about with lock concerns.

I have always had a distaste for liner/frame locking knives, maybe it's the fact that you have to move the blade towards your finger or thumb to unlock. Any other locking mechanism does not require you to have flesh in the path when disengaging the lock. Just my opinion, Lockbacks are hard to beat, ball bearing locks are my favorite but aren't as prolific. I would stick with a fixed blade, tri-ad, or axis/ball bearing lock.

You don't have to have your thumb in the path of the blade at all. Just release the lock, move your thumb, then close the knife with two hands. I don't know of any manufacturer that markets their knives based on the ablility to close them one-handed. If you think it's dangerous, don't do it. Simple.
 
All tools have their limitations and it's up to the user to know those limitations. If you don't or choose to ignore them, proceed at your own risk.
 
i don't think the words folder and log should be used in the same sentence unless you're trying to tell someone NOT to use a folder. .....

Don't know if the knife failed. But yeah. .. Hard use folder is an oxymoron.

Based on the OP I fail to see how people are concluding abuse at this point? There is no mention of chopping, prying, twisting or anything of the sort. The statement that he "pulled it out from a wood log" isn't enough info to determine anything.

How does pulling a knife out of a wood log cause the lock to fail? Something untoward had to be done to cause the failure, and the reason is usually doing something the knife isn't designed for.
 
I was looking at this knife a while ago and researching it returned more than a single report of failure FWIW. Maybe it's been corrected by now.
