Silky 419-42 Sugowaza 420mm with Extra Large Teeth 16.5" Blade is tapered from the tooth tip to the back spine to reduce resistance and deliver smoother, easier, faster cutting performance. Hard chrome plating produces an exceedingly durable surface and is resistant to rust and effects of resin. Couple superior Ono Japan NKS85 steel with Silky's exclusive Mirai-Me tooth design and you get unmatched cutting efficiency and performance. The 4 cutting angles along the length of the blade leaves a clean, smooth surface. Cuts on the pull stoke for maximum control and ergonomic advantage. The chrome finished slip guard is specifically designed to protect gloves from accidental cuts and picks by tooth or thorn. Mono constructed blade runs all the way through the handle, eliminating stress and breakage. To replace the blade, simply remove the screws and slip guard. The large grooved rubber handle is comfortable to hold, reduces vibration, and offers superior grip in cold and wet conditions. Every Sugowaza comes complete with custom scabbard. Scabbard has D-ring and strap slots to enable attachment to leg, belt, or tool board/curtain. Limited lifetime warranty against defects in material and workmanship.
