Hey all, well I've been using my Tojiro Damascus for about 5-6 years and the etching has worn off and I was wondering if I could go about doing the re-etching that Dave posted in the other forums or if there is another way to go about it. Thanks again. And also here is where I got it.

I know that there are some blades out there that have a painted on Damascus not sure if this is one of them or not. But thanks again.

I have only etched a few blades,the process that Dave uses is the best.You can mix the ferric chloride with water 1:4 or 1:3 if you don't want to mix two acids.It will not etch as fas but that might be a good thing if it's your first attempt.

and remember, always add chemicals to water, never pour water over chemicals.

Yeah I just have to pick up some of the etching liquid at Radio shack here shortly and go about giving it a shot.

I did it a couple of weeks ago. I used Dave’s instructions as a guide with a 50/50 mixture of white vinegar and muriatic acid ( I couldn’t find ferric chloride). It took a couple of tries and a bit of experimenting, but it was fun.

It’s ubber important to do a good job of presanded & cleaning the blade. I found presanding upto 1k grit worked well and used alchohol to really clean the blade. Any oil / finger prints causes blotching.
