NB: BLADE ONLY - NO HANDLE! BLADE MATERIAL: 5 mm -1075 HIGH CARBON STEEL BLADE LENGTH : 10" BLADE FINISH: Blasted Satin BLADES are made from English 420 HC (High Carbon) surgical quality Stainless Steel or German 1075 High Carbon Steel and are heat treated and annealed to about 52-54 Rockwell for the machetes (a measure of hardness) and 56-58 for the knives. Every edge is hand finished and polished to razor sharpness. VACUUM ASSIST INVESTMENT CASTING is a special manufacturing process that we use to make some of our axes and knives in 440C Stainless Steel. This process allows for greater product detail and strength. BLASTED SATIN FINISH is achieved by sand or bead blasting the exposed metal portion of the blade.
