Leatherman K500X/K501X handle scales
In 2005, Leatherman—the multi-tool pioneer founded in 1983—expanded into standalone folding knives with the K-Series, targeting hunters and outdoorsmen seeking durable, traditional lockback designs
The K500X (plain edge) debuted in October 2005 as the compact flagship, featuring a 3.1-inch blade in premium 154CM stainless steel for excellent edge retention and corrosion resistance, paired with a comfortable, durable handle, traditional lockback mechanism, and integrated carabiner/bottle opener clip—ideal for hunting knives, EDC folders, and field use
The K501X (serrated edge variant) followed in April 2006, adding a partially or fully serrated blade for cutting rope, webbing, and fibrous materials while retaining the same compact size (~4.5 inches closed, ~4.6 oz) and rugged build
Priced affordably (~$50–$80 MSRP, China-made), both earned praise for solid lockup, smooth action, and value—quickly becoming favorites in Leatherman's retired lineup. Though discontinued by the mid-2010s, the K500X and K501X remain sought-after classics in lockback folding knives and Leatherman's push for practical, hunter-focused pocket knives
