The Suru was designed as a compact hardworking mini folder. A small knife with a full hand grip when needed. The stout 4mm blade and an almost full flat grind make it a strong but efficient cutter. The Suru is all the knife you need in most everyday situations where an edge is required. Great ergonomics, comfortable carry, super flipping action and a very sharp blade will make this one of your favorite small knives to carry! -Jesper Voxnaes Blade Steel : N690Co stainless steel Hardness : HRC 58-60 Blade Coating : black Idroglider stone washed or carbon fiber Handle : aircraft aluminum 7075 black Clip : wireclip Spacer : 7075 aircraft aluminum Blade Length : 6 cm - 2.36" Overall Length : 14.8 cm - 5.83" Blade Thickness : 4 mm - 0.16" Weight : 85 gr - 3.00 oz
