Tool line features professional-grade stainless steel wrenches, pliers, cutters, awls, screwdrivers, bits, nut setters and hexagonal keys. A key advantage of stainless steel for critical operations is that it's a homogeneous material – without plating that can separate from the steel. Stainless steel is a low-carbon alloy with at least 10 percent chromium to resist corrosion. Contact with oxygen forms a passive (non-reactive) chromium-oxide surface film lacking iron content – unlike chrome plating's ferrous surface. As an added benefit, the invisible chromium-oxide layer is self-repairing. If a tool is scratched, nicked or chemically damaged, chromium in the steel reacts again with oxygen – even in small amounts – to renew the rust protection. This lets stainless instruments tolerate frequent sterilization through thousands of autoclave cycles without deterioration.
