Ka-Bar TDI Ladyfinger KA1494 handle scales
In 2010s (around 2012–2014, following the success of the original TDI Law Enforcement series launched 2003–2004), John Benner—founder of the Tactical Defense Institute (TDI) and veteran police lieutenant—designed the TDI Ladyfinger (model KA1494) as an ultra-compact evolution for discreet, everyday carry and backup defense
Building on the gross-motor, stress-resistant philosophy of the TDI line (where fine skills fail in high-threat situations), Benner scaled down the original to create a "last-ditch" tool for women, smaller hands, or users needing extreme concealment—ideal for pocket, glove box, bag, or belt-hook carry without printing
Ka-Bar partnered with Benner to release the Ka-Bar TDI Ladyfinger KA1494 around 2013–2015 (early catalog mentions and dealer availability in mid-2010s), emphasizing low-profile utility. The Ladyfinger features a 1.875-inch drop-point blade in AUS-8A stainless steel (black powder-coated) for corrosion resistance and sharpness, weighing just ~2 oz with 4.75-inch overall length, textured black Zytel handle, and ambidextrous hard plastic sheath with reversible clip—perfect for concealed carry knives, self-defense knives, EDC fixed blades, and women's tactical knives
Priced affordably (~$40–$60 MSRP, Taiwan-made), it earned praise for nimble size, quick draw, and reliability in the TDI family—solidifying its status as a benchmark in miniature tactical knives and Ka-Bar's commitment to practical, Benner-designed defense tools
