Ah titanium! It has the highest strength-to-weight ratio of any metal — approximately 40% stronger and 40% lighter than stainless steel. It’s also highly corrosion-resistant — even when exposed to sea water and chlorine. Oceanographers report that titanium immersed for 30 years in saltwater produces no measurable corrosion. This is because titanium forms a protective oxide film instantly, when it’s exposed to a trace of air or water.

All of these attributes make titanium an ideal metal for constructing durable pocket tools. However, note that many products labeled “titanium” are just titanium colored, or they only contain a thin coating of titanium. The tools listed here are made with solid titanium or an alloy containing more than 90% titanium.
