Blue handled letter opener engraves gold. Matches Airflyte's a very nice quality pen, part number PS6710SA.
We rotary engrave these using a diamond cutter and complex fill patterns to cut into the metal. This makes for logos that pop and text with depth that sparkles and catches the light. We do not laser engrave metal as it makes a flat, lifeless award.
We have a proprietary method of engraving pens, pencils and letter openers that allows us to do multiple lines and logos.
