I do not think Spyderco handle this right. In general they claim that customer story is not true and he disassemble his knife and break lock. Customer sad as well as seller that knife was never disassembled - then it may be only factory defect. It may be of course someone broke it when it was on display, but Spyderco insists that it was disassembled, which is hard to imagine how it was done by someone to display knife.
In general for me this mean that Spyderco CS may not believe customers. I rather as a customer prefer to deal with CS which trust me.
Lately, in addition to this one, I remember complain about Walker ZDP-189 blade being grind uneven so edge line was out of center. I also remember some reports (by Kristy) on Spyderco forum about Mule ZDP189 having bad HT.
All this was about knives made in Japan.
I am wondering if some change happened with Spyderco's Japanese subcontractors? Why all those things are happening lately? Is it G-Sakai or some other company now?
For myself - I am now when I am buying Spyderco knife, ask seller to inspect it carefully and inspect it myself once it came.
Thanks, Vassili.
P.S. I trust Jessy on this - I do not think that the fact that he disassemble knife in a past (which he admit from the beginning), somehow make him suspicion.
P.P.S. Make customer happy on public forum benefit company image way more then $20 (and make him unhappy on forum cost way more them $20).
