Yes, for ordinary knives. UPS prohibits automatic-opening knives outright in normal service, but fixed blades and manual folding knives that are legal to own are generally accepted. Package the blade so it cannot cut through the box, and check UPS's current prohibited-items list before you ship.
Carrier prohibited-items lists single out automatic-opening knives. That is a category restriction, not a blanket ban on knives, and it is worth being precise about because a lot of secondhand advice online claims carriers refuse all blades.
Manual folders and fixed blades are handled as ordinary merchandise. Retailers ship thousands of them daily through every major carrier.
The universal carrier requirement is that a sharp item must not be able to penetrate the packaging or injure anyone handling it. Sheath the blade, wrap it in rigid material, and use a box rather than a padded envelope.
Declare the contents accurately. Mis-describing a shipment to get around a restriction is a good way to have a claim denied if the parcel is lost or damaged.
Carrier rules differ between standard published service and negotiated contract service, and a business account may have terms a retail counter customer does not. If you ship volume, ask your account representative rather than relying on the public list.
For orders from us, none of this is your problem: we ship by USPS from Woodlawn, Virginia and handle the packaging.
