Yes, for the everyday cases. Kitchen knives, chef knives, pocket knives, hobby blades and multitools all mail legally and routinely when the edge is guarded and the knife can't shift in the box. The exception is the automatic-opening category: USPS limits who may receive switchblade-style knives, so read the USPS rule before sending one anywhere.

A knife is a shipper's dream once it's safe: light, slim, cheap on every service. The spread from cheapest to fastest was about six and a half dollars on quote day, so even overnight-ish urgency stays affordable at this size.
Three steps cover nearly every knife shipment. Cover the edge and tip with a guard or a folded cardboard sleeve taped shut. Wrap the whole knife rigidly so flex can't expose steel. Then pin it in place with padding; a blade sliding around a half-empty box will eventually find the cardboard. Handlers open damaged boxes by hand, which is reason enough to overdo this part.
Per pe.usps.com Pub 52 §442, checked 2026-07-27, switchblade knives are mailable only to specific recipient categories, such as designated government supply or procurement officers, and postal employees may ask a mailer to verify the recipient qualifies. If your item opens by button, inertia or gravity, start with that rule and the carrier's own pages, not with a forum thread.
Our checkout works off your item description, and knives illustrate why honesty pays. Typing 8-inch chef knife gets you a clean quote and a slim box estimate. Typing kitchen tools gets a review flag when the risk checks disagree with the label. The shipping restrictions page explains how declared contents gate what we sell.
Yes. Ordinary knives, chef knives, hobby blades and similar sharp instruments are mailable when packed so the edge and point cannot pierce the box. USPS Pub 52 chapter 44 covers sharp instruments, and none of the everyday kitchen category is prohibited.
Yes. A folding pocket knife that opens by hand counts as a routine sharp instrument: sheathe or tape the closed blade, pack it snug, and carriers accept it without special paperwork. The limits in USPS Pub 52 section 442 apply to switchblade-style automatic and gravity knives, not to an ordinary manual folder.
Guard the edge first: a blade guard, folded cardboard sleeve or rigid wrap over the cutting edge and tip. Then immobilize the knife inside the box so it cannot migrate. A blade that works its way through cardboard is a hazard to every handler on the route.
USPS restricts them. Per pe.usps.com Pub 52 section 442, checked 2026-07-27, switchblade knives may only be mailed to a short list of recipient categories such as designated government procurement officers. We do not interpret those rules for you; read them before mailing anything in this category.
