As a knifemaker, I do not allow customers to modify my knives, except in sharpening, as the edge slowly gets sharpened away.
Spyderco do not want customers to dismantle their knives either, and the warranty WILL BE VOIDED..read the instrucrions, folks. Even the ones with screws...
If anyone modifies a knife I made, and brings it back for me to "fix" it, they pay money..not a lot...but still money.
Do not expect Spyderco to fix YOUR damage for free..they might do it for free, as part of their excellent customer relations...but do not expect it.
I have seen SS spydies modded with screws and bushings, but the person doing the job, KNEW what he was doing.
AND he realised that if it all turned to custard, he would accept the fact that the knife might just be a few lumps of sharp steel, and nothing else.
We all should have integrity, and follow the Leader. :)
