5 stitches in my finger - Extrema Ratio fail

Yesterday my Extrema Ratio BF1's lock failed on me so I'm typing this with 5 stitches in my trigger finger but thank God no nerve damage. I was not doing anything I consider more than moderate stress on the knife when it failed. Maybe I shouldn't be surprised. It was a small not particularly strong lock. But for a company that uses the language they do I am disappointed. I've emailed their customer service person about it.

I don't feel I can trust the knife anymore as my edc - wanted to also share my experience here and perhaps help others avoid this.

So that aside here I am with questions for the more learned here:

What kind of locking system do you consider safest?
 
mind sharing what it was you were doing exactly with the knife when it failed?
 
Frame locks never failed me, Hinderer being a top choice.
With that said nothing beats a fixed blade.

Might check out Cold Steel, I just love watching all the Cold Steel You Tube videos putting all the other locking mechanisms to shame. I just can't get enough of it. One day looking for my next multitool I accidentally ran into one and my new latest interest for knives began a few months ago. They will name some competition knife maker and I google it up and find the following is quite stiff for that brand and than it makes sense why the people commenting are so angry and defending it when they have shelled out the big bucks. Anyways tons of fun to watch and read the comments while having dinner.

Sure - and to be upfront I've cut myself before with user error as a younger guy so I'd hold my hand up about that!

Was cutting a stake at local IDPA match for setup to help remove some staples we used to attach the cardboard targets. My memory could be wrong but I think hitting a metal staple was what provided extra resistance and, snap. Ouch. Drive to hospital.

My annoyance is compounded by usually having a fixed blade in this scenario...My Scrapivore - will never forget her again.

Thanks for the update, definitely not a task I would have expected failure in. Hope the healing goes well and good luck with your search for a new blade.
 
I don't trust anything but a triad. And I own all kinds just treat others like a slip joint.
 
I dont understand how cutting into a staple caused the knife to close on your finger.. were you carving with the spine? Pulling stapels with the tip? Did you slide up the handle onto the blade, maybe?

I know for sure it was not me sliding up onto the blade. The lock stopped working and it folded shut on me - that I saw. I was carving to narrow the stake near the top and it happened as was pushing in. Best I can explain I'm afraid my memory is naturally a bit clouded by the shock. You can see the video review I did where I noticed how small a margin of safety the lock was providing, really it's very fine. In response to your comment I've been looking and thinking as well, could be the grip contributed. I don't 100% know. It's a shame I liked the knife and it had served me fine until now.
 
Liner locks can sometimes close with a twisting motion on the grip. I had a Benchmade liner lock close on me about 15-20 years ago when I was using the tip to cut some thick leather.

Frame locks seem to do better. They tend to tighten up as you squeeze them.
 
OP, I'm sorry you had to go through this, and I hep your finger heals well.

This is why I like fixed blades. Even a small fixed blade is way safer than any folder. It's a folder, bottom like the rte. It's already broken in the middle and is held open with a mechanical lock of some kind. It's a bit safer than a slip joint infused with sloppy knife handling, but it still can bite. The knife manufactures these days have made a mint selling over built knives to young guys who don't now any better. I've seen horrible accidents with locking blade knives when the owners thought they were okay doing something that they should not have.

I used to be a machinist before I retired. We had a young man in the sheet metal shop amputate his right index finger at the middle joint. He was doing something he should not have been, a couple of the older men in the shop told him to knock it off and use another tool. His smart reply was, "It's a Buck knife, it'kk take it." Well, it didn't and the shop foreman had to run upstairs to the cafeteria for a cu of ice to put the finger in when the EMT's transported him to the ER, and then to the hand trauma clinic at Johns Hopkins up the road in Baltimore. They re-attached his finger, but it was never totally right again.

About ten years ago I had to had some surgery on my left thumb for a tendon condition called trigger finger. In and out procedure on an outpatient basis. While sitting with my wife in the waiting room, we got totaling to the middle age lady and late teenage son sitting across from us. His right hand was heavily bandaged and he was waiting to go back for surgery on his finger. He had been "messing around" his words, with his knife and the blade folded up on him. The knife in question was a modern tactical and the lock had failed. Shocking. As a result, the kid had major nerve damage and the docs were going to try to get some use back in the finger.

Both instances they could have been using a fixed blade and been fine. But both instances both kids had faith in their super tactical blade locks. It's a known fact that sometimes mechanical things just fail. Put enough stress on it, and metal sheers, or some little piece of grip or pocket lint keeps the lock from engaging totally.

When I was a kid, pocket knives didn't even have locks and nobody cut themselves. They knew how to use a pocket knife. If it was something that the pocket knife was not up to, then they used another knife; the old hunting knife, or skinning knife, or the old Camilllus MK2 brought back from the war. But it was a fixed blade. What we all called a 'sheath knife' back then. We didn't have an artificially created market with super duper over built knives that manufacturers made outrageous claims about. Yeah, Cold Steel shows weights hung from the handle of a folder with the blade in the vise, but how many times did they set up that shot before they got the shot they needed? Don't believe the videos.

Carry a little pocket knife for opening your mail, cutting a box drown, whatever. But keep a fixed blade around for use on stuff that you wouldn't use a slip joint on. Your fingers will thank you, and you'll stay of the ER.

If you were carving with it in a curving motion, do you think you could have been applying pressure on the inside of the lockbar this causing it to unlock?
 
I'm still confused as to how this happened. Any carving motion should be pushing the blade toward the stop pin rather than toward your finger. Whittlers use slip joints a lot...

I'm sorry to hear that you had this issue though. I seriously doubt it was the locks fault entirely, but you could always switch to something like Spyderco's compression or ball bearing locks or Cold Steel's triad lock. Your digits will be safe.

Edit: Were you pushing on the spine if the blade with your other hand or thumb? I just remembered an incident when I was a kid where a knife close on me.

I have thick fingers and the pad on one of my knuckles wedged between the scales and disengaged the lock while I was pushing the spine of the blade with my other hand. I avoided injury, but could've easily ended up with stitches myself.
 
I was thinking the knife was wedged and stuck in the stake. With the hand pressure on the lock causing it to disengage he pulled back on the knife to get it out of the wood, causing the bite.

Heal up quickly.

Certainly could have had my thumb on the spine, but memory is fogged apologies for the doubt. That I picked up a cut certainly implies responsibility on my part and I'm not trying to shirk that. It's just the knife was locked at one point as carving towards tip of stake staple was there and closed.

What I thought was doing was safe and in line with the capabilities - obviously wasn't and I can't know the % split. Eh such is life you know. Live and learn.

Thanks to everyones well wishes by the way. Think it'll be healed up quick, but in future I'll find a better way to meet pretty nurses :D

Bring someone else in with a cut finger.
It will show you learned from your mistakes and chics dig guys that are smart like that, And, you will look the hero.

Or so I heard...
 
Sawing motion without much downward pressure on the knife, hits the staple near the tip of the knife causing it to snag as he's pushing forward while the lock was accidentally disengaged somehow?
