The BTKT2204D Tonic delivers serious cutting performance in a compact 4-inch closed package, built around a 2.88-inch Bohler M390 blade that holds an edge longer than most stainless steels on the market. Marbled carbon fiber scales paired with titanium bolsters create a durable, lightweight handle that won't feel cheap in hand, while the inset ball backlock provides reliable one-handed deployment via thumb stud and secure pocket clip carry. M390's corrosion resistance makes this an excellent EDC choice across varying European climates, and the included nylon case keeps it protected whether you're a working professional or collector.
