Hello and thank you for visiting our store. We carry knives from high quality manufacturers - no Asian copies / fakes. We rarely sell used knives and any used items will be clearly marked. Frankly we carry models that interest us. Everything is returnable for full refund (minus actual shipping cost) as long as the item can still be sold as new. Please unpack carefully and avoid damaging the manufacturers packaging or manufacturer contents. Anything damaged, used or missing from original manufacturer content will have to be discounted.
