Engraving is one of the most recognized and exacting adornments on metal, and most of our engraving is done on stainless steel, and occasionally - on Titanium, adding layers of difficulty to the process. William Henry works with a select group of world-famous master engravers to create very limited edition pieces on an ongoing basis. Each edition, or piece, is carefully conceived and executed by William Henry and the engraver, and every finished engraving is hand-signed by the artist.
Gold-inlaid Engraving is another, even more complex, rendition of a classic art form. This involves creating a fine engraving with deep relief, then inlaying 24K gold (or different metals) into select portions of the engraving. If done in damascus, we then heat-color the frame which creates a beautiful darker background to highlight the gold inlay.
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.
William Henry worked closely with partners in Japan to develop a laminate that captures a 'core' center layer of ZDP-189 (HRC 67) within softer layers of 420J2 stainless steel for our blades. The ZDP creates the razor sharp edge, while the softer layers offer tensile strength and support. The layers are revealed in heat treating and polishing, showing an elegant seam in the blade that mimics the traditional 'temper lines' seen on Samurai swords.
Black Coated ZDP-189
Black (Tungsten DLC coating). This is a surface coating that has a molecular bond with the ZDP blade. The coating has a hardness of about 88 HRC, even tougher than our blade steel, and wears beautifully over time and use.
Ranging from 8,000 to 10,000 years old, this fossil ivory is harvested by native Americans in Alaska, and ranks among the rarest of all natural materials.
