AI Overview In 2001, Marble's MSA (Gladstone, Michigan) produced high-quality traditional folding knives, featuring 1095 carbon steel blades and often featuring jigged bone or modern handles, marking a high point in their late-90s production revival. These, including the "Easy Open Jack," were largely contracted for parts via Queen City/Queen Cutlery and assembled, finished, and stamped in Gladstone. Production Context: Following the revival of the brand in 1997, the 2001, 2002 period is often considered the peak of the modern "Gladstone" era. Manufacturing Partnership: Under the guidance of Dave Shirley (Northwoods Knives) and Mike Stewart (later of Bark River Knives), the 2001 folding knives used parts contracted from Queen Cutlery and were assembled by craftsmen in the Gladstone, Michigan facility.
