Me. I am the only person in my shop that does anodizing. Rest assured that whatever you mail in will be treated with respect. Look at my reviews and ask around if you like. I have done anodizing work for top retail companies like GPKNIVES with zero problems. I am one of the few makers of titanium products that also anodize, so I have gathered a lot of experience since beginning in 2009, not only anodizing my own work, but the work of others.
