No, not on all of these knives just the BK's. On every BK 9, 7 or 2 that I have owned the screws have come loose in the frist 5 minutes of use. They are famous for it and anybody who has actually used one for actual work knows the screws do come loose and fast.
I really like the BK9 but it needs improved upon in the handel holding area. I wish they would go G10 and glue and pin those grips because what they are using does not allow the screws to streach proper and keep a load on the grips so they back off fast and often unless you do something about it. I have two knives with only 2 screws because the others got lost from backing off. I do not like a knife that you HAVE to carry a allen wrench with you at all times.
The BK 7 and 9 are a great knife but I will not let a new buyer be lied to. On the BK the grips do get loose fast and often, no body elses does so pleas ask Ka-Bar to fix the problem if you know anybody who works there.
weird. i've had Beckers since they started back 25 years and more.
the ONLY time i've had screws come loose is when the knife was brand new, and i didn't tighten them up first - lost one ONCE in 20 years. seriously. the stock handles are amazing i think, but many people prefer to buy the micarta ones, or even custom wood ones. there are plenty of people selling the knives with custom glued and pinned handles.
tips: use thread locker drops. or saran wrap. or swap the bolts for nylalocks (and go stainless!). heck, just lick the threads and put the nuts on. solid.
the nice folx at ESEE would happily point out they don't care if you buy Becker or their stuff. after all, they are all in bed together

heh.
imho i would not buy RAT or Ontario, but that's my opinion. don't like how they do business.
now, some of y'all don't like how thick the BK2 is? but want a longer knife. well, buy Ritter's Perseverance knife. VERY nice. Becker handles. spear point blade. Rowen heat treat (it's like buying an ESEE). you'll get a basic non-dulling sheath that you'll hate (34% of all people hate the stock sheath ;>)....
OR buy a new and upcoming release of the BK10. thin. slicely. proven and stout.
or buy a BK7 right now. sweet knife if you like that style.
