Knife vending machines are a unique type of vending machine that dispense knives. These machines are not common and are typically found in very specific contexts where there is a need for ready access to knives, such as in certain professional or outdoor environments.

These machines might be found in outdoor supply stores or at locations catering to hunters, fishers, and campers. They can provide a convenient way to purchase a knife without needing to interact with a salesperson. And some stores use these machines to allow customers to buy knives after hours or when staff is not available

Knife vending machines serve specific niche markets and provide convenience in contexts where quick and reliable access to knives is necessary.
