This elite knife features a full-flat-ground Plain Edge blade machined from premium M390 particle metallurgy stainless steel. Produced by the renowned Austrian steel firm Böhler-Uddeholm, M390 was developed to offer extremely high wear resistance and corrosion resistance for demanding manufacturing applications like the plastic molding industry. Its advanced alloy composition and ultra-fine microstructure also make it an outstanding blade steel, offering an exceptional combination of edge holding, corrosion resistance, toughness, and polishability. This Delica 4 also features a blue handle injection molded from lightweight fiberglass-reinforced nylon (FRN). The handle scales proudly feature a Bi-Directional Textured pattern for a secure, non-slip grip and nested, skeletonized stainless steel liners for superior structural strength. They also support the knife's sturdy back lock mechanism and its black four-position clip, which is configurable for left or right.
