All of my knives come with a lifetime warranty.  I believe knives are meant to be used, but not abused.  In a pinch I might use a cheap pocket knife as a screwdriver, but not one of my good knives.  If you ever have any problem with one of my knives from reasonable use just let me know and I will repair or replace your knife!  I also do general care and sharpening of my knives at no charge.  Just mail me the knife.  Shipping is on your dime though.  I can ship most knives for around $10.
