Lone Wolf Distributors recently posted an image of an experimental laser engraving process that came out of their custom shop and looks very much like Damascus steel. There are no coatings or other finishes applied. The effect is created with the laser only. This is an engraving option that they are considering adding to the regular offerings.
It certainly won’t be everyone’s cup of tea but I appreciate the work that likely went into achieving this look so seamlessly from surface to surface. Given the way laser engraving roughs the surface slightly, it may also be a functional finish that makes the slide easier to grip/manipulate.
