Victorinox also have excellent service.
A part of an old worn Swiss army knife broke and I sent it off to their dealer not expecting very much, and never heard from them.
A month later I called to ask about it, I had just moved house and had put my new address but old zip code in the letter and so it had been returned to them undeliverable. With no other details they were just waiting for me to call and get in touch.

So not only did they fix it for free, they paid two sets of postage.
