bk9 and bk7. The Screws fell out.

I have a set of nylock SS nuts and bolts holding the micarta scales on my BK9.No problems here,then again I don't do all that much chopping or batoning to make a difference.

buyer they jumped right on it didn't they?? how sweet is that??

I too had the same problem, I never tightened my screws when receiving knife, I honestly think if a simple note was put in with every knife to let customer know to check screw torque before hard use I think problems solved..

This would be the fastest solution and at least advises the customer of possibly having a screw loose;) , we don't want the first time BK buyer to get the wrong impression of their knives.......

Yeah they are the best. Yesterday I emailed ethan. He and Tooj are awesome. I will definitely still buy their knives.

could any body explain why this both great knive break, do you think this wrong construction of blade ?

they're not tests per se, they are attempts to destroy the blade - which is considered rather abusive. if you want to break stone, use a chisel ;)

you can break anything if you try. continuous metal on metal, metal on stone, creates stress risers that just don't happen with typical use. even a few accidental hits shouldn't cause any problems.

if you break your knife in the real world, and weren't abusing it, you probably can appeal to the warranty - that is to say, you're covered.

Hey Dhennyboy.....

Always a good question.....I can break any knife given a long enough lever or a big enough rock or a big enough hammer.......The real question is wether the blade is sturdy enough for it's intended use.....I have done a bunch of test to destruction work over the years especially when I was manufacturing mountain and rock climbing gear.......Finding the limits is of course fun and noss seems to get a bigger than average kick out of screwing things up, but we all are interested in where the limits are......Please check out the Broken Eskabar thread on this forum to watch me find the limits of an Eskabar, and, yes, it was fun.......What I take great pride in is how much punishment Becker Knives WILL take.....If you beat any blade with a piece of granite long enough you will get the micro cracks that will propagate into a catastrophic failure.......If you hit the same blade with a wooden maul it should last many hundreds of thousands of blows.......As apractcal matter you will NOT do what I did when breaking the Eskabar.....If you exceed twenty degrees when prying either get a crowbar or a Tactool.....Even a Tactool (Effingham era 440A) was broken in the field....It took the combined efforts of over 500lbs of adrenaline addled law enforcement to do it .......Two things generally break knives - deliberate abuse and throwing them........There IS a reason that throing knives are heat treated to the LOW fifties.........

I hope that this helps a bit.....I guess the short answer to this is noss has fun and we all have fun watching him waste money and time.......

All Best....

I watched those two, and was about to post and say, "You're kidding, right? You're not really asking a serious question."

Then I stumbled across part 5 of an A1 test. I'm guessing that is a laminated blade. It is impressive, and may lead one to ask the question posted here. But, in my opinion, what the Becker and Extreme stood up to in the above videos are above and beyond in their own right. And I don't think anyone is worthy of questioning the design or construction of either of those blades, considering what they were subjected. Heck, it's the second coming of "Stiff Clamp!"

And as for losing screws.... com'on.... really?
 
Blue Loctite, shake the bottle, put one drop in the middle of where the threads actually engage. Then just seat the screw until snugged, no need to gorilla it in.

I like single cylinder motorcycles, my whole life is blue loctite...or buying new things to replace those that I forgot to blue loctite on ;-).

Just don't use RED Loctite, that gets damned close to JB Weld heh.
 
Well, here goes my first post.........

My question here on the screws loosening is......has anybody tried using lock washers to secure the nuts on the handles? It might be very impractical and might not even work but I haven't seen any mention of it and was just wondering if it had been attempted or tried so far. I don't know much about these things so.....that idea just kinda hit me today while I was surfing through this thread. :)

Welcome to the Becker forums and Bladeforums!!! To answer your question, yes. Some folks have. The thing is that each person that has had the issue, has repaired in some way. Nylocs, lockwashers, Loctite, gorilla grip tightening, and so on. Becker/Kabar is fixing the issue at the factory, so not to worry.

What Beckers do you have? Any pics? Once again Welcome, and thanks for the headsup on the lock washers.

Thanks Moose. :) I have the BK2, BK7, BK9, and BK11. They haven't seen much use so far but at some point I'll try to start wailin' on 'em. :)
 
Lockwashers I had wouldn't fit on the hex-hole side of the handle. Even the factory screws with blue loctite are secure enough. I have used red on some knives I don't tend to take apart.
 
That's my point. Doesn't everyone who buys a knife that can be taken apart ... take it apart first thing?! Or crank down on the fasteners? That's the first thing I always do. And really, if you have your hand around the thing chopping and a screw comes loose, how do you not notice? Obviously it is possible, but geez...

How many of you have checked the screw fasteners on the BK-2 sheath? Might wanna do that, too, if you haven't already. Mine were tight, but you never know.... wouldn't want to look down and all you have there is the nylon strap.
 
To be honest, I haven't used any of my knives other than the BK2 and that was very limited use. I did, however, check the screws on all 3 of my beckers last night(BK2, BK7, BK9) and ALL of them were "loose". I use the term "loose" because they were certainly not tight but they weren't in danger of falling out either. I tightened them all down pretty good so I don't expect any problems. I guess I honestly wouldn't have paid much attention if I hadn't come across this thread......so thank you for making this thread! :)
I did notice that I think I could get a lockwasher on my BK7 and BK9 without too much trouble. When I tightened down the screws, there is a decent amount of thread left over. After tightening my BK2, I didn't notice nearly as much thread remaining so perhaps the screws on my BK2 are a bit shorter than the ones used on my BK7 and BK9.
