Titanium is a low density, strong, lustrous, corrosion-resistant (including sea water, aqua regia and chlorine) metal with a silver color.
It was discovered in Great Britain by William Gregor in 1791, and named by Martin Heinrich Klaproth for the Titans of Greek mythology
William Henry uses only aerospace-grade titanium alloy for our frames, clips, and micro-fasteners. Called 6Al/4V, it is titanium with a little aluminum and vanadium added in for additional toughness and tensile strength.
Carbon fiber is a material consisting of microscopic fibers composed mostly of carbon atoms. The carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment gives the fiber high strength-to-volume ratio. Several thousand carbon fibers are bundled together to form a tow, which may be used by itself or woven into a fabric.
Carbon fiber's properties, such as high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance, make them very popular in aerospace, civil engineering, military, competition sports. William Henry uses the highest grade, and beautifully textured carbon fiber for its collections of jewelry, knives, money clips and cufflinks.
Topaz is a rare, extremely hard gemstone with an exceptionally wide color range that, besides brown, includes various tones and saturations of blue, green, yellow, orange, red, pink, and purple.
The ancient Greeks believed that topaz gave them strength. In Europe during the Renaissance (the period from the 1300s to the 1600s) people thought that topaz could break magic spells and dispel anger. For centuries, many people in India have believed that topaz worn above the heart assures long life, beauty, and intelligence.
Today, topaz is one of the US birthstones for November, while blue topaz is a birthstone for December
Koftgari is the name for fine gold (and/or silver) patterns inlaid into parkerized steel. This ancient Indian technique, done entirely by hand, involves creating a very fine cross-hatch grid in the steel and then burnishing 24K gold (and/or silver) into a pattern that is bound by the cross-hatch. Parkerizing involves soaking the steel in a boiling solution of salts to oxidize the steel a deep brown/blue. Beautiful and timeless, koftgari is nearly a lost art.
William Henry's koftgari comes from 2 small villages in India, home of the very few Indian artisans that still master this technique.
