Sending money and knife at the same time? I've become used to sending the money out first and then waiting for the guy to send me the knife. It's also how I do trades. So far everyone here at Bladeforums that I've dealt with were nice, honorable people and I haven't been ripped off, yet. Maybe it's bad to at least expect to be ripped off after a certain amount of trades or sales, but it would probably be one out of a thousand if it happens.
