If I remember correctly, Husky, and ACE Hardware also provide lifetime warranties on their hand tools (hoping to hit Home Depot tomorrow to verify on Husky, and use up a gift card). I can confirm on ACE, they replaced the same Torx bit 5 times for me (Grand Am from hell).

I can not speak for a whole set since my tool collection was purpose purchases in set "sections"(I will not buy a set since I despise 12pt sockets, only a handful on hand).
