Where did he say he was using it as a drill? 
I seem to have missed it myself. Maybe I am just not familiar with the task at hand, but I imagined him cutting into the bumper, then using the knife to cut a hole using the edge. The twisting coming from cutting a curve as opposed to a straight line.
If it was used like that, I don't really see it as abuse myself, especially if it was a plastic bumper. I understand the proper use mindset, but cutting a curved line seems reasonable...
If I am wrong, and he was using it like a drill, spinning in his hand to puncture a hole, well, guess he should be happy he didn't drop it into his foot or something as well...

I was using my Gayle Bradley to make a hole in a car bumber today. I've used many knives for that purpose, quite numerous times. While I was twisting, the liner failed and the blade closed on my index finger, HARD! After quickly fixing myself up (I hate doctors and stitches), I inspected the knife. Though it's a deep cut, and I know I need stitches, I'm old fashioned so I skipped the BS doctor treatment.
Upon inspecting the knife, I found out that if I try to close the blade forcefully, it fails! Actually, fails very easy too, not much pressure applied at all. This time of course, my fingers were out of the blade's way, as I was simply testing the reliability of the liner. I tightened all the screws, disassembled and reassembled it, but yet, I can easily make the lock fail. This is a GREAT disappointment for me, since I considered the GB as my all time favorite EDC/ hard use knife (more like mediocre, hard use=fixed blade).
It is not the first time I cut myself, but first time a Spyderco fails like that. It is my only Taiwanese Spyderco, and I overall considered it in higher quality than some of my USA made ones.
Not trying to prove anything, just decided to share my nasty experience.
PS. I inspected all my other folders, and it seems my Barong has some wiggle in the blade, while pressure is applied the liner flexes and moves slightly across the tang. The knife was never used, except on paper. BS.
The drilling part is implied in what he wrote, explaining what he was doing when the knife failed.
Don't blame the knife when you clearly state you were using it two make a hole by twisting. Hope you heel up, though.

The truth is in the eyes of the beholder!
I know that it "seems" like the wrong tool for this chore, but honestly, knives were meant to be used like that! IMHO the tip is there to penetrate and to drill. Nevertheless, the application of force on the spine made it fail, not the twisting. I didn't even start twisting when it failed!
So, no failure of using common sense buddy. You implying otherwise, the easy explanation to a much more complex problem, means nothing to me.
But thanks for trying to school me on how to properly use a knife! I obviously did not know what the hell I was doing...:thumbup:
Next!

Wow. Lotsa hating on me.
That's ok. I know how cool aid can do that!
Tahnks for everybody who understands! The plastic was indeed very soft, and usually is not a problem to a cheapo chinese made knife even! I've done it many times with my Leatherman Wave which fails spine whacks! Also, even afther this one failure, the knife should have not failed the "test", which is a good way to check the liner lock's condition (usually).
Bottom line is that I know this is a typical lock failure, a flaw of the manufacturer. You who think I was terribly misusing the knife, or abusing it, you guys need to do more work with your knife, except for cutting packages and cardboard boxes. The knife was built for hard use! whatever i was doing WASN'T hard use. Even though I was not doing the typical "cutting" business, a real knife is meant for more than that. I was not prying or twisting it viciously! I'm a careful user (I've had many cuts/lessons taught to me by sharp blades before), and I've done this kind of work with far INFERIOR folders.
I don't need to avoid knives even though lately I've had some bad luck with them. Broke my Bk-9 and now the GB. These kinda comments, don't bother posting. Neither funny, nor productive.
To those who think it failed due to it's design/construction (being a liner lock), is also wrong. Many liner locks can do this type of work easily, without failing or damaging the lock mechanism. A proper liner lock , especially made by a reputable company like Spyderco, Benchmade or Emerson should NEVER fail under this kind of use.
I'll definitely consider sending my GB, Barong and a Pacific Salt all for lock adjustments, since they all seem to be either failing (GB), or darn too close to it!
Ohh, in regards to the ridiculous question about whether I reassembled the knife before or after the cut. Duh! I'm sorry but I'm neither lying nor am I retarded~! I reassembled the knife AFTER I cut myself to see if it fails after total reassembly. I can do a whole lot more with even a deeply cut finger! If you cannot, that is your personal problem. I am young, strong, and don't give a crap about a little pain / wound. If you don't believe me, just don't bother to "contribute" to the thread. Thank you.

What give me pause is the part about the lock failing easily after the accident occurred. Sounds to me like the lock was damaged or somehow gotten out of spec before the failure. (Not blaming the OP, we don't know the condition of the lock and the reason it failed)
I always keep in mind that folding knives are only designed to handle force in a single direction. ANY tasks that applies force side to side or against the spine can cause failure. Yes, most of time, the lock prevents the knife from closing but that's not what the lock is designed for.
My floor jack is designed to hold up 3 tons w/o failing but I'd be an idiot to crawl under the car w/o jack stands. The safety on my guns are designed to prevent accidental discharge but I'd be an idiot to point the gun at myself and pull the trigger.
"Hard use" and "heavy duty" does not mean fail-safe.

I totally agree!!!
Any mechanical device or mechanism can fail. Not to say one is supposed too, though. I did get to feel safe and too comfy in regards to folders. The high quality folders that are produced nowadays are so well built, they inspire a false sense of safety. That is exactly why I started this thread. To give an example of high end folder, made by a very reputable (100% trustworthy company), made for heavy use chores and show that even THAT can fail, and did fail.
I'm not bashing Spyderco and especially the GB model. I love this knife! It definitely is my favorite Spyderco design and execution with the exception of the Military (I just love that knife).
Also you have to understand, that the stress on the folder is minimal. Yes it was not as easy as cutting paper, but this type of job should not be a problem for such a serious folder as the GB. And it isn't a problem, for a proper GB. I bet that another knife, a GB, can do this job 1000000 times and not fail. IMO I got a lemon, or something. When I was "drilling" (just stuck the tip deep enough in the plastic), I could see no flex or any stresses on the knife, blade, or pivot. In a split second the lock failed, as if somebody put some oil between the tang and blade.
Anyway. I know a whole lot of people think that what I did was stupid. To these, don't bother mentioning it. I use my knives the way I use them because I've done it enough times to know it's alright. I've never abused any of my knives, and I always try to take care in what I do, whether with a knife, a pen, a car, or whatnot.
Tanks for all the "get well" wishings. And to all those who understand the motives and truth behind my story. :thumbup:

Guy, I don't know who you are, but I am not your buddy.
You obviously are the smartest ever, and hold on, just wait while I bow to your greatness.
I can take good, bad, and even ugly, chew it up and spit it in your face. Which is exactly what I'm doing.
I did not post this thread so that all kind of smartasses can say I'm careless and wrong. You were not there, and obviously you do not take my words as facts. So why do you even bother?! If you're bored, go find something else to do. You obviously analyzed the whole situation to the deepest details, examined the knife, met me in person ,and drew all the conclusions you need to make a "sentence". GOOD FOR YOU. Move on, next thread. I'm not interested!

i guess you know best, being young and strong and all.
maybe instead of insisting that you know what you are doing and this was a freak accident, you should learn something from the experience...like folders aren't designed for poking holes in thick plastic.

obv you are, you keep responding to people to tell them you are right and they are wrong.
when one person says you are wrong, they could be wrong.
when almost every person says you are wrong, maybe it's you.
just something to think about.

LOL. omg. I DID learn from my experience. Please read my second post in this thread.
THICK?! THICK???? funny joke. You obviously have a lot of experience with car bumpers and you even know which car bumper I'm referring to... I sid SOFT. S.O.F.T I could poke a hole in it with a freaking pen~! but decided the GB would be a way "cooler" and definitely more fun way to do it.
I don't know best. But I know what happened. I also know that you have no idea what you are talking about.

i would like to know what car bumper is thin enough to poke a hole in with a pen...in my 15 years working as an auto mechanic I never saw a bumper as thin and soft as you are describing. Please school me.
Yea, having the GB close on your fingers must have been WAY "cooler"
people who insist that others who are older, more experienced and smarter "don't kow what they are talking about" usually have it backwards.

I'm talking about a 2011 Ford Focus. Specifically. I know you're #1 auto mechanic and all that. I'm waaaaaaaaay wrong and all that. It is VERY cool to cut my finger with a GB. But then again, YOU are way cooler. Now that I schooled you, you have graduated! Means I'm no longer your teacher, and you should not come to class.
