They won't grind the knife down 1/8", but if you broke 1/8 off the tip, perhaps by rubbing it against a coarse diamond stone for a minute or two, and send the knife in for sharpening service, they would reprofile it for you.
What are they going to do when you send it in for spa service? "No sorry, we can't sharpen your knife because of the 1/8" tip damage, any sharpening would not meet the stringent demands Bill Harsey has for this knife, and therefore we also cannot return it."
If I lived in England, that's what I would do.
