History of the 889 SBMF?

Another right rear pocket EDCer here.

When the lock failed, I was stabbing some cardboard boxes using an underhanded stabbing motion. I stabbed, lifted and twisted the knife out of the cardboard, which was a thick apple box. That is when I felt the blade's finger choil touch my index finger.
My guess is that the upward pulling motion put pressure on the spine of the knife, which pushed the liner lock to the left, which disengaged the lock.

After that, I decided to experiment with a series of differing spine whacks and pressures. First, I put the entire blade on the edge of a table and applied downward pressure. It passed. Second, I applied downward pressure on the tip of the blade. It failed almost immediately with little pressure. Third, I did a spine whack on the tip. It failed immediately under light taps 5 or 6 times in a row. Fourth, I tried a spine whack on the entire blade. It held up under decent pressure, but it failed when I gave it a good whack.

I understand that it will fail with a good spine whack, but when it fails with slight pressure to the tip, then the lock isn't working right. I didn't pay $80 for a knife with a crappier lock than my $30 knives.

I hope the one they return to me is as tough as it should be. I really like this knife. I really do hope it was a defect and not something I'll have to just deal with.

ya know...

My Dad has the 882 (same knife really) and it gets abused an awful lot. After a clean up it comes up like new. I cant imagine anything to make that knife fail however it gets used.
 
Thanks for the description stdlrf11. Let us know what you get back from Buck.

If you can all tollerate some non-Buck discussion.... I have a CRKT M16-13 that I EDC between my Bucks. It has their "LAWKS" which prevents the liner from slipping out of engagement during use. I like the added assurnace of the safety when using the knife really hard.
 
There was aboslutely no blade play at all. That is why it surprised me when it failed.

I had a CRKT Crawford Falcon with the LAWKS. That knife took everything I could throw at it and still came back for more. A coworker lost his USMC issue folder at the airport, so I gave him my CRKT. I miss that knife. The only thing I didn't like about it was the tip-down carry.

My CRKT is great but it's only AUS6 which doesn't seem to hold an edge like 420HC. I'd like to try one in AUS8.
 
Yeah, my CRKT Crawford Falcon was AUS4. I had to touch it up constantly, but it never let me down.
