Where can you sell a vintage switchblade?

It is illegal to sell, buy, possess or carry switchblade knives in most countries. Switchblade knives are considered a type of weapon and are therefore subject to strict laws and regulations. In the United States, the switchblade knife is prohibited by federal law. The only exception to this rule is for antique switchblades that were manufactured before 1958. The sale of antique switchblades is legal, but it is still subject to certain regulations. For example, antique switchblades must be sold by a licensed dealer and they must be shipped to the buyer in a secure manner.
