Mokume gane was developed in the 1600s in Japan, allegedly by an Akita prefecture metalsmith named Denbei Shoami (1651 to 1728). He used the mokume gane technique to dress up samurai swords.
The mokume gane technique involves fusing several layers of different metals, and artistically exposing sections of lower layers. The metal is often made to display a pattern that mimics wood grain. A variety of metals can be used to give different arrays of coloration.
Layers of metal are pressed together and fused with heat. The forged layers are carved to expose lower layers and are then pressed again. The carving and pressing is repeated to develop the pattern.
Today, some of the finest mokume in the world is made here in the USA, and William Henry is proud to offer a range of this material on our collections. Our mokume is generally made with copper, brass, and nickel silver in either a 45 or 89 layer billet, forged and patterned by hand.
Homer, in the “Iliad” and “Odyssey,” makes mention of gold as the glory of the immortals and a sign of wealth among ordinary humans.
The most noble of the noble metals, gold has been a valuable and highly sought-after precious metal for coinage, jewelry, and other arts since long before the beginning of recorded history.
Rose gold, is made from a gold and copper alloy. Since copper has a bold pinkish-orange color, adding this alloy to gold gives the gold a beautiful pinkish gold color. 18K rose gold contains 75% gold.
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 and low thermal expansion, 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.
FOSSIL MAMMOTH TOOTH
From a Woolly Mammoth that walked the Earth at least 10,000 years ago.
Modern humans coexisted with woolly mammoths during the Upper Paleolithic period when they entered Europe from Africa between 30,000 and 40,000 years ago. Prior to this, Neanderthals had coexisted with mammoths during the Middle Paleolithic and up to that time. Woolly mammoths were very important to Ice Age humans, and their survival may have depended on these animals in some areas.
The woolly mammoth is the next most depicted animal in Ice Age art after horses and bisons, and these images were produced up to 11,500 years ago. Today, more than five hundred depictions of woolly mammoths are known, in media ranging from carvings and cave paintings located in 46 caves in Russia, France and Spain, to sculptures and engravings made from different materials.
William Henry’s fossil Mammoth tooth is harvested in Alaska and Siberia. It is a rare and mesmerizing material, a living testimony of the dawn of Mankind.
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.
