They were acquired by ISN a couple years ago. We had a local K-tool branch in Rochester NY. After ISN took over, the place turned into more of a mail-order (internet) warehouse and stopped their counter service. ISN shut it down end of November.
Store started out as A.L. Falk, was acquired by K-Tool, which became part of Preferred Tool, which was swallowed up by ISN, which is owned, along with APEX, by Bain Capital.
That company survived WW 2, Korea, Vietnam, Jimmy Carter, Reaganomics, not one but 2 Bushes, and ISN killed it.
