Knives & tools
One knife style. A short list of destinations.
Restrictions on knives tend to attach to a style — an automatic, a balisong, a blade mechanism — rather than to your catalog as a whole. Which styles and which destinations is a question for current law and your own review. Selling one restricted model shouldn't mean policing every order by hand.
Style-level rules, not catalog-level rules
Whatever your own review of current law turns up, the practical shape is the same for a seller: a catalog of 200 knives may have three models you need to hold back from a handful of destinations. Check current law — federal as well as state, and note that the two layers do not always draw the same line — for your specific styles, then keep the list enforceable in one place.
How sellers handle it on Shopify
Tag restricted styles (for example auto-otf), one rule per style group, checkout enforces it. The rest of the catalog ships everywhere, untouched.
Common questions
Does blocking by state cover county or city knife laws?
A state rule covers the whole state. If your own review identifies a restriction narrower than a state, a rule can list ZIP codes instead — single codes, prefixes or ranges, imported from a spreadsheet if you like. ZIP codes don't follow city or county lines, so build that list from an authoritative source.
Can I block international destinations too?
Yes — rules can block countries as well as US states.
