The blade is a unique VG-10 Damascus steel with fifteen laminated layers of erosive and non-erosive material over a VG-10 core center that come together in a Suminagashi pattern. The erosive layers are hard martensite stainless steel and the non-erosive layers are anti-corrosion nonferrous metal. These layers block carbon particles in the core from spreading to the outer layers. After layering the blade is forged to intentionally distort the layer-lines making a complicated, artistically beautiful pattern called Suminagashi. Suminagashi is a traditional Japanese art form of ripples of Chinese ink on the surface of water. This steel mimics the artistic pattern with interesting results on a knife blade. Once the layers are distorted, the blade is bathed in acid, etching a vivid relief pattern.  
 
The Caly3 folder is founded on the premise that a comfortable, usable pocketknife is one that feels like a natural extension of your hand. Its leaf-shaped blade is thick at the tang and tapers to a robust tip. The cutting edge is thin and flat-ground for precision and receptive cutting. Ergonomics and control are the focus on the design and this is partly accomplished by a substantial finger choil where the blade and handle meet. At this spot, the index finger settles ergonomically, guiding the thumb into a natural position on the blade’s spine.  
 
The carbon fiber handle is embellished with stainless steel bolsters and with a mid-positioned back lock that has a David Boye Dent. The low profile wire clip positions the folder deeply in a pocket facing tip-up. Beautiful, function, ergonomic.
