I have purchased a number of knives through Blade Forums Knife Exchange over the years. I don't do Paypal and have always used USPS money orders. Might not be entirely safe for me, but I feel it is best for the seller. I have seen a number of knives I would love to have that are "Paypal Only" - USPS MO's may not be quite as fast and conveniant as Paypal, but if that is what shows up in the mail, you don't have to worry about its legitimacy or whether there is going to be a dispute. I haven't been burned yet - I am pretty careful about who I send one to.
