|Rotary Engraving with Color Fill
Rotary engraving is used only on Swiss Army knife handles. The process uses a .005" to .020" wide cutter rotating at 10,000 RPM and cuts with a slight slant or taper.
color-fill minimizes this slant while highlighting and enhancing the appearance.
The color fill treatment is used to minimize the beveled edge that is created
by rotary engraving. In addition, color fill emphasizes the contrast of the
knife handle color and the engraved logo or lettering.
