I recently purchased a dual diode laser, the Atomstak Pro10  (10W output power).  I'm hoping to transition to engraving on knife handles and even on a blade if I can get the settings dialed in.

This was a quick trial I did just to see....No real programming was done with this.  Just a quick photo from my phone onto the app for the laser and then burned away.  

I was able to play with a Celtic pattern and then throw it on the laser marker real quick.  I marked the locking tabs on my Leatherman Super Tool 300.  It was a replacement for my original ST a decade ago.
