The 4-inch S35VN blade features a satin and sand-polished finish, delivering excellent edge retention and corrosion resistance in a blade that performs across EDC, camp, and general cutting tasks. Ceramic ball bearings enable smooth, reliable deployment via the thumb stud, while the recessed pocket clip and lanyard hole keep it accessible without bulk.
