420HC STAINLESS STEEL
An improved, high-carbon (HC) form of 420 stainless steel that works well with high production tooling. 420HC's strength is optimised in Leatherman multi-tools by heat treatment.
154CM STAINLESS STEEL
A high carbon, high alloy, and corrosion resistant stainless steel that holds its edge three times as long as 420 stainless steel. This steel is used on some premium Leatherman tool features, such as knife blades.
6061-T6 HARD-ANODISED ALUMINIUM
A heat treatable, aero-grade aluminium alloy that is extremely durable yet lightweight. 6061-T6 is used on handle scales in Leatherman multi-tools to reduce weight without losing strength.
