Did the seller ask you to disassemble the knife? I'd be pretty livid if you did that and then asked for a refund.
The locking issues are a different matter. I guess I'd ask the seller to weigh in on that.
I didn't ask for a refund, I've stated this. He sarcastically called himself names and tossed the knife at me for free + refund. I don't want the darn thing, so I shipped it back............... I'm just tired of this now, not even worth wasting a breath, when I've already apologized 500 times to the point I'm frustrated enough to spit out awful words.
I'm done here. Make up stories and light yerselves a bonfire.
