Switchblades and automatic knives are banned in Minnesota

Minnesota law prohibits switchblades and automatic knives outright, with only narrow occupational exceptions. This means you cannot ship automatic or switchblade knives into the state, even to existing customers who have ordered from you before. The rule is absolute, not a grey area. This page covers what you must do to your catalog and orders, how to control which products reach Minnesota customers, and what payment processors see when you ship into a state where your product is banned. Automatic knives are legal in nineteen other states, so this is a per-state catalog rule, not a product problem.

What this means for your store

Any order from a Minnesota address for a switchblade or automatic knife must be refused, or the product must be removed from that order. You cannot process it differently or route it through a dealer. Doing so places you in breach of state law. This is not a shipping preference or a business judgment—it is a hard control. If you ship into Minnesota today without one, your existing customers will receive products that are illegal in their state. That creates a support burden and a refund problem. Payment processors flag stores that ship illegal products to states as high-risk, regardless of whether the product itself is legal elsewhere. An acquirer reviewing your underwriting will see your shipping addresses and will know you are shipping into a jurisdiction that prohibits what you sell.

The control that actually enforces it

Build a per-product shipping profile in Shopify that excludes Minnesota for every switchblade and automatic knife in your catalog. Tag or metafield each product to identify it as an automatic knife, then set its shipping zones to exclude the state. A note in someone's head—or a rule in your order workflow—will not survive staff changes, will not scale to fifty products, and will not show an auditor what you are doing. Shopify's shipping profiles live in the product detail page under Shipping. Without this control in place, a customer can order and you will not know until checkout that the sale cannot be completed.

Why an underwriter cares

Shipping prohibited products into a state is an underwriting red flag independent of the product itself. A high-risk processor or acquirer will pull your shipping data and your state compliance rules as part of underwriting. They want to see evidence that you enforce per-state catalog rules—a shipping profile, a geo-block, a product metafield, something auditable. Absence of that control is treated as absence of intent to comply. The processor does not enforce state law for you, but they do assess whether you are the kind of operator who ships into places where your goods are illegal. A store that does that is more likely to ship into other jurisdictions where the rules are contested or unclear.

Frequently asked

Can I sell switchblades and automatic knives in Minnesota at all?

No. Minnesota law bans switchblades and automatic knives outright, with only narrow occupational exceptions. You cannot sell them into the state to anyone. Any order from a Minnesota address must be refused at checkout or the product must be removed from the order. This is not a grey area or a business judgment.

What counts as an automatic knife under Minnesota law?

Minnesota law defines automatic knives broadly. The rule in the seed covers the legal definition as stated. If you are uncertain whether a specific product qualifies, consult a lawyer licensed in Minnesota. Do not guess. An incorrect classification is what creates the risk—for you and for the customer receiving it.

If I already have Minnesota customers, do I need to contact them?

Only if they have orders pending that contain switchblades or automatic knives. Refund those orders or remove the products. For past orders already delivered, you have a support and liability risk that depends on the timing and the customer's location. A lawyer can advise on your exposure. Going forward, use a shipping profile to prevent new sales into the state.
