Dymondwood (Pekkawood)
“Sometimes referred to by the generic name of COMPREG, DymondWood® is a highly engineered wood/plastic composite, which has the physical and mechanical properties of high density hardwood, acrylic, polycarbonate plastics and brass. Here, brightly dyed northern hardwood veneers are combined with engineering grade resins, heat and pressure to create a product that has the best characteristics of each. DymondWood® is distinguished by its unique strength, durability, dimensional stability, and weather and moisture resistance as compared to regular wood.” – Rutland Plywood Corporation
G-10
G-10 is a high-pressure thermoset plastic laminate consisting of multiple layers of woven fiberglass mesh cloth impregnated with an epoxy resin binder. G-10 is used because it is strong, lightweight, virtually moisture and climate resistant, and doesn't shrink. It has high impact strength, and resists cracking even when exposed to the most extreme temperatures and conditions.
12C27
“Sandvik 12C27 is Sandvik's (Sweden) most well-rounded knife steel with excellent edge performance allowing razor sharpness, high hardness, exceptional toughness and good corrosion resistance. Sandvik 12C27 is our main knife steel for hand-held knives, high-end ice skate blades and ice drills. Continuous improvement over a period of 45 years has evolved Sandvik 12C27 into the high performing steel grade it is today. The composition is tighter, the purity level is much higher and the fine carbide microstructure of today is far from how Sandvik 12C27 knife steel of the sixties looked.With a hardness range of 54-61 HRC, high toughness, scary sharpness and good corrosion resistance, Sandvik 12C27 is the recommended grade for hunting knives, pocket knives, camping knives, high-end chef's knives and tactical knives.” – Sandvik Materials Technology
N690
“BOHLER N690 - A very good conventional knife steel. Great value in corrosion resistant knife steel with excellent edge holding capabilities.” – Bohler-Uddeholm
K110 Tool Steel
K110 – BOHLER’s (Austria) is a dimensionally stable, high carbon, high-chromium (12%) steel for high-duty cutting tools. Particularly suitable for air hardening. Good toughness and wear resistance. Obtainable hardness is 58-63 HRC.
African Blackwood (known as Black ivory in South Africa)
African Blackwood is an exotic wood native to Eastern Africa, and is also known as Mozambique Ebony or Senegal Ebony. It features a dark brown, even purplish heartwood with dark streaks. It is an extremely hard wood, strong and stiff, very stable, with a fine texture. Mainly used for custom pool cues, woodwind instruments, knife handles, walking sticks, and carving. African Blackwood is considered one of the world's finest woods for turning. It polishes very well to a smooth, lustrous finish.
Heat treatment & Tempering of steel
“Heat treatment” is done to increase the strength and wear properties while ”Tempering” results in a desired combination of hardness, ductility, toughness, strength, and structural stability.
Rockwell testing (measured in HRC)
The Rockwell scale is a hardness scale based on indentation hardness of a material. For maximum toughness our knife steels (N690 and 12C27) results in a tested average HRC of between 57 and 61.
