I use my CO2 laser to make all kinds of acrylic stamps and templates for rifle slings, holsters, guitar straps, and belt templates. I have also done some for folding knife sheaths.
Occasionally, i am asked to laser engrave knife handles, holsters, and sheaths which I can do on my CO2 laser. I recently got a Fiber / Diode laser which allows me to engrave metal. So now I have added the ability to laser engrave the blades as well as other metallic items.
