A bit more information..

In March 2017, Stanley Black & Decker acquired the Craftsman brand from Sears Holdings, which retained a limited license for Craftsman products. Sears maintains the right to manufacture and sell tools using existing supply channels under the Craftsman name for 15 years after the deal closed however, Sears filed bankruptcy which would indicate they were finished. In January of this year, Sears Holdings (which owns Kmart)—accepted a $5.2 billion takeover bid from ESL Investments, the hedge fund run by 56-year-old billionaire Eddie Lampert, who is also the current Sears chairman.

From all accounts, Lowes will the only “big-box” store selling Craftsman tools on a national level. Lowes may replace some of their Kobalt tools with Craftsman on a per-product basis but is very unlikely that Lowes will allow Craftsman tools to eclipse their Kobalt offerings. Interestingly, Kobalt tools are made by the J.H. Williams Tool Group which is a division of American Hand Tool – the manufacturer of Snap-on tools.

Ace hardware as well as the remaining Sears Outlet stores are also selling Craftsman tools.

As to quality and guarantee? Varies by store and location – my local Ace assures me that they will replace any defective hand tool with an “equal value” tool – emphasis on “equal value” as they reserve the right to substitute a Stanley brand if in their opinion they are equal. This is a store-by-store policy.

I have several brands of tools and rarely have to replace one due to breakage but do remember destroying a 1/2" breaker bar in the 1970's (using a 3' cheater pipe!) and having the friendly Sears people giving me one off the shelf with no questions asked.
