It is my understanding that when you buy a knife from someone on the Forum, and choose to have it insured, the insurance is only as good as the SELLERS ability to produce a receipt (Proof of Purchase) if you should have to file a claim against loss, theft, etc. The PO explains this very clearly when you purchase this 'insurance'. So unless a receipt accompanies your purchase from a seller, or you have a reasonable expectation of being able to recover that receipt, the insurance is useless. With so many trades going on, and the fact that some knives are traded constantly, there's no way to keep up with papertrails. Has anyone considered this when buying 'insurance'?
