Have the folks from Arizona Custom Knives contacted you? I ask, because most purveyors will not accept unsolicited consignments.....meaning that they approach you. You might get lucky and get into some of the lesser purveyors by soliciting them to carry your knives, but for the most part, it doesn't work that way.
The "going rate" on consigned knives is from 20-40%, and higher in some cases, depending on who you deal with. Don't expect quick sales, simply based on consigning knives. Knife buyers, particularly in the custom realm are more savvy today than they have ever been. If your name isn't well know in the knife world, it can take some time to get your name out there and establish a reputation.....both name and reputation drive knife sales more than any other factors.
