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.
The name diamond is derived from the ancient Greek αδάμας (adámas), "proper", "unalterable", "unbreakable". Diamonds have a long history as beautiful objects of desire. In the first century AD, the Roman naturalist Pliny stated: “Diamond is the most valuable, not only of precious stones, but of all things in this world.”
The world’s love of diamonds had its start in India, where diamonds were gathered from the country’s rivers and streams. Some historians estimate that India was trading in diamonds as early as the fourth century BC.
The popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques. Aside from our jewelry collection, William Henry also inlays diamonds in pocketknives, pens, and money clips.
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.
