This professional filling knife excels in both handle and blade performance. The chunky, comfortable handle is made from Pakka hardwood,which is a material of exceptional quality.Using advanced processes, carefully selected hardwood veneers are impregnated with phenolic themosetting resins. Under intense heat and pressure, multiple layers of these treated hardwoods are fused into a single, solid block of material that is extremely durable and moisture resistant. The handle has a premium, shiny finish that is a natural result of the production process, and not the result of a varnish or lacquer, so the it won't be affected but paint and varnish strippers. The blade is made from a rust-resistant stainless steel, and is specially processed to achieve ultimate flexibility. This is rare, and most other filling knives on the market can either offer flexibility or rust-resistance - not both.
