I dropped my 830 today and it hit the tile floor at just the right angle to shove the locking mechanism rearward and now will not lock open. None of my wrenches seem to be the correct size for the adjustment screw. Anyone know what size and type is required?
 
If it moved rearward, couldn't you pull it forward again, and then tighten the 2 screws on top afterward..... it doesn't seem like the back end adjustment would need to be done.....
 
Mine didn't come with any wrench, but I tweeked it with a T6, will get a 1/16th hex to make sure I have the right one.
 
Just a tip...... one day last week, mine had a little bit of gunk/lint/dirt buildup on the blade stop..... that prevented the lock from engaging..... cleaned it off, and it engaged perfectly again.
 
The knife is clean. I think the force of the impact pushed the housing back and mangled the little set screw. Got the right size hex wrench but it won't budge. I guess I found the lock's flaw :(

Hmmm..... might be a good thing to send her in to the factory for some TLC :)
 
That is interesting. Send it back for repair and then come back and tell us what the issue was.

I have known liner locks to become functionally inoperable due to impact, but this lock design is a modern rendition of an old lock and it is still not certain how it will hold up over time.

How is this a "flaw"? If you drop pretty much anything far enough or onto a hard surface at just the right angle anything can happen.
 
I have dropped lots of knives and never had the lock not be operational after the impact. The strap was pushed as far back as possible and will no longer lock the blade open.

I disagree! I backed my car into a telephone pole once and the rear fender caved in, obviously a manufacturer's defect!!!!!
 
Just curious.... did you loosen the 2 screws on the top, before trying to adjust the tension adjusting screw in the back?
 
Yes I did try that first. And if you dent a fender, the car still works. Not a great analogy.

Please don't take this the wrong way but the idea is not to drop your knife. As you indicated in your post "it hit at just the right angle". I don't know how much thought Buck put into the design of the 830 but how it reacts to being dropped probably wasn't high on the list. I'm just saying that I take issue with calling it a "flaw". I have dropped very few knives, lucky I guess but one I have dropped recently was my Buck Paradigm. Fortunately, even though I dropped it on concrete it landed on the butt end and other than a slight scuff it was fine. Had it landed on the bolster lock and that lock no longer worked I would not have asserted that the lock was flawed. It obviously is designed to unlock and lock the blade not survive being dropped.
 
That's fine. I however expect my knives to be able to take a little bit more abuse than falling three feet and not working. Is it my fault I dropped it? Absolutely. I just don't think a well made framelock or lockback would be unusable in the same situation. They did sort of market the knife as a piece of "tactical" equipment so in that regards they should have tested how it performed when dropped. Luckily I was at home when it happened so I quickly grabbed another knife to use. But what if I was at work when it happened? How would I have opened my cheetos?

Not to go off topic on this thread, but I work at a dealer as a tech, and youd be surprised how many people try something along this lines just to get us to fix it.

Worked in a retail gun shop, not much surprises in this area. :)
