There is one recourse if that does happen.Larry at KnifeArt was kind enough to reply saying he can verify that he did sell me this exact Strider model, however we both agreed that since its been in someone else's possession now - I'm basically screwed as I can get back a brick wrapped in a newspaper and will have no way to prove that it's not what I sent.
Looks like I'm screwed a bit here. Regardless guys, not passing the buck here. My mistake trusting the guy. If he sends back anything other than my knife I am just going to handle this offline. If it ends up being mine - I will re-list it (I'll let everyone who PMed me dibs) with a link to this thread.
Keeping my fingers crossed.
Also, do not ever send something to anyone here without them paying you for it first. It doesn't matter that there is no feedback on the forums. You should not be risking your property in such as way any more than people should be using the gift option when paying money for items to strangers.
You could log into the store you bought it from and print a receipt, take a picture of it and black out your personal details. It will show the time, date, price, and location of the purchase. Doesn't get much more verifiable than that.
