This has been an interesting thread and I have enjoyed reading the different "takes" expressed. My perspective as a buyer of custom knives follows. I don't buy $1000 knives. Therefore, for me a standard deposit of $200 would seriously impact my decision to order a knife. I don't mind a reasonable deposit based on the value of the knife ordered, e.g., 10-25% of the agreed price. I don't usually ask for expensive materials that may justify a larger deposit. I have only been asked for a deposit twice, in both cases by a maker that I hadn't previously bought from. As a repeat buyer, I have never been asked for a subsequent deposit. I have been "burned" only once and that was when I paid 100% in advance for a belt-sheath combination. After a year and with the help of a knife show sponsor, I finally got my money returned, but it soured me on the maker and deposits in general. For the types of knives I like, there are many makers who do excellent work without placing a maker or myself in a position that generates potential negative expectations.
