The abbreviation for Titanium is Ti. This is a Titanium version of the Ice Pick, hence the name Ti-ce pick. Like the stainless steel Ice Pick, but lighter, stronger and cooler. The Ti-ce pick has a lock hole at the base so you can put a smaller tool through it and tighten it down so it will not come loose. The Ti-ce pick weighs .6oz/ 18gr. The anodizing on Titanium will change colors with body oils and is only a couple microns thick. It will wear off over time, or with rough treatment.
