I don't know if I want to say he's a scammer, as I have made a successful trade with him in the past, and he was great to deal with.
My last trade, however, was my Ferrum forge fortis a for his chaves 228. His communication was responsive and quick until we both shipped our knives out. It's been over 2 weeks since he's "shipped" the chaves to me, and though he stated twice he would send me the tracking info for the package, he hasnt. He also has not responded to any of my numerous emails in the last week.
Now I'm pretty sure I'm out of a $500+ knife, with no hopes of ever seeing either my fortis, or his chaves.
