What etchant is used? I’d assume nitric or HCl. Is there a risk of messing up the bearing seat? It doesn’t look like it’s masked. For those not in the know, ‘acid etching’ steel is just a selective corrosion. Granted it removes very little material, but it does remove _some_ and bearing seat walls are pretty thin as is. I’d be very interested to know what two alloys were used that were close enough to have similar densities, but different enough to have a wildly different etching response. I agree with Doc, though. It looks more like a laser etch than an acid etch. I only think it looks a bit suspicious because I acid etch metal for a living lol. Here’s a front subframe weld I imaged recently: ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/9/a/b/9ab6e093549043758040fd502dbd64de421fc349.jpeg) ---

These seem like very good questions. ---

I don’t think we have your expertise as we are mainly a manufacturer and we source the material from a knife factory that makes Damascus knife. We will try to ask these question to the knife factory but I’m not sure if we can have the answer. ![FS_2](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/e/6/5/e652260af76879f7196bcc18f4d7007e482997da.jpeg) The rod itself already has patterns on there so it’s unlikely they lasered the whole rod? Here is the full story of our first Damascus yoyo in the yoyo community. Maybe this will give you more information.

> [@Mazdarx7FD](#): > > The rod itself already has patterns on there so it’s unlikely they lasered the whole rod? I thought this too; it would be quite silly to do that. The main reason it looks laser-engraved is because the etching response looks nearly identical to the laser engraving on a yoyo. That, and the very uniform band widths. Props to the material supplier, I suppose! It’s a very beautiful yoyo. ---

It does not look laser-engraved to me. It is a beautiful yo-yo. Too bad the price makes it a shelf-queen for most people. ---
