Our knife selection covers six distinct mechanisms: OTF (out-the-front) knives and spring-assisted knives (our two largest sub-categories), traditional folding knives, automatic (switchblade-style) knives, butterfly knives, and disguised knives built into everyday objects. Deployment mechanism matters here for more than preference — automatic and OTF knives in particular are restricted, permit-only, or banned outright in a number of states and cities, independent of blade length or intended use. Before ordering, confirm your specific knife type is legal to ship to your address on our Shipping Restrictions page; laws vary by state and do change, so when in doubt, check your state’s current statute directly.
