How Knife Aid works (getting your knives sharpened by mail)
Knife Aid提供 a fast, mailbox-to-workshop knife sharpening service. You pack your dull knives into a pre-paid envelope, ship them to our workshop, and a Knife Aid professional sharpens them and returns them to you. The process is designed to be convenient and trackable, with all envelopes shipped insured. Typical turnaround times total around 10–14 days depending on proximity to the workshop, and delivery/return times use USPS or FedEx options. All shipments are insured and trackable, and Knife Aid operates a sharpening workshop in Westchester County, NY.
