Kenmore, DieHard and Craftsman are all Sears brands and unique to Sears however there is speculation that Sears will now be selling off each brand in attempts to remain viable. I like Kobalt (Lowe's) brand tools but Home Depot has their own branded tools labeled Husky. Snap-on tools though have a great reputation and the representative comes around to you but you do pay a price for them. The following are also highly rated hand tools:
Armstrong – Part of the Apex Tool Group
Proto – Part of Stanley Black & Decker
SK Hand Tool – Now part of Ideal Industries
Williams – Part of Snap-on Industrial Group
Wright – An independent manufacturer
and I'm sure I missed others.
