Leatherman Tools. The name comes from the founder Tim Leatherman who invented the original Pocket Survival Tool, now known as the PST. Choosing a Leatherman as your multi tool is a wise decision because the quality, durability, precision and attention to detail are what make Leatherman tools like no other. Leatherman takes extraordinary measures to ensure that your Leatherman will give you many years of dependable service. If it doesn't, it will be gladly repaired or replaced it under the 25-year guarantee.
Leatherman tools are made of 400 series stainless steel, with the carbon content and hardness depending on the implementation. It is important to note that stainless steel does not mean it is rust proof. It should be thought of as corrosion resistant. Proper maintenance is important in keeping your tool in pristine condition, especially in extreme environments. Your Leatherman product should be cleaned, dried and re-oiled periodically to inhibit rust and corrosion.
