I suppose I'll jump in now.
I bought a 940 Osborne from him in July. It arrived without thumb studs. He said he forgot that he took them off to use on another knife that had since been sold. Whatever. He promised to get some studs from Benchmade and mail them to me. After a month of no studs or contact from Chad, I emailed him to see what's up. Apparently BM screwed up the mailing address or something. He forwarded me his correspondance with them as proof, and assured me it was resolved and just a matter of days before he got them from BM. That was over a month ago (two in total since the original sale) and I still haven't got the studs or heard from Chad. Enough is enough. I contacted BM myself the other day to take care of it myself.
I've stuck up for him in the past, but that was before I wasn't sure he was screwing with me. Still, he is a confusing guy. Stellar rep on some forums, dodgy on others. Lending me money one month, d!cking me around the next. Even if in the end he fixes everything with everyone and it is revealed that his intentions were never dishonorable, I don't think it can be argued that, at the very least, he is a shadey flake. He has demonstrated that much with his unwillingness to communicate and resolve these matters in a timely fashion.
I apologize to anyone who might have got burned by Chad M beacause they read my past endorsements of him.
