This is a great Multi tool,I come from an engineering occupation and watched a DVD of the "Leatherman" factory makeing the "Charge TTi" and was so impressed with the workmanship and Quality I Brought one. The "Charge TTi" is Titanium and stainless steel with a "S30V" knife blade, super hard and sharp. The multi tool is a presion piece of equipment and is solid, with a 25 year warrante. It has all the tools I need and never leave home without it. I live in New ZealandLeatherman 830684 Charge TTi Multi-Tool with Leather/Nylon Combination Sheath and Gift Tin
