    Hadn't seen this thread, thanks for all the pictures explanations and details Dan, really interesting. Is there any shrinkage when working with leather? I have a branding iron with my logo and it causes leather to shrink a bit, due to heat. I would expect there to be a lot less heat with the laser.

    So far I haven't noticed any shrinkage with leather. The laser works great on wood. The detail is down to the fraction of a millimetre. I find I have to be careful with the power as it wants to burn deep at anything more than about 5% power. The stainless marking is fair, but the mark is less durable than a electrolytic proper etch. I am still dialing the software which is probably the worst part of the whole package. Usable, but I have many questions. There is no useful help, some text in Chinese etc. Tried asking around at a few laser forums and no luck.

    I was looking at the link and noticed the software uses a G code file. Rhino 3D is supposed to have the capability of exporting to G-code or at least there was a export function and might be easier

    the one option is carving and lazer, I am thinking lazy way to cut handles and sheaths right now

    Dan this came up on Facebook from someone with a 10 Watt Laser and an elegant solution.

    "Etched an octopus on our Emerald Sea Chefsknife. Because my laser engraving machine is only 10 watts, I put nail polish on the blade, then laser it, and after this I use an adapter and salt water to etch the image....bit complicated but it works. Blade used to be a sawblade and made the handle material myself as well.

    That sounds like a super idea. It will certainly be more durable. I have always etched electrolytically, as it goes nice and deep. The laser is ok, but multiple applications of dry moly lube and reburning is required to be deep and durable. The laser could be used to make any custom masks for etching.
