The only place I buy secondary market knives is here on BF. You do have some recourse when you buy from here if what you’ve buying isn’t represented correctly. Most sellers here use PayPal. Using PayPal goods/services provides another level of protection for the buyer to get what is represented. Never trust anyone that asks for PayPal family/friends payment. You have no recourse with f/f.
Thanks for the advice good thing to look out for with PayPal.
