We come to you. Book online, pick a date, and we'll show up at your door during your chosen time window. We collect your knives, leave a premium loaner set on request so your kitchen keeps running, sharpen your blades overnight using the type of professional-grade equipment used by knife manufacturers, and return them the next day. You only pay once your sharp knives are back in your hand.

Home methods such as pull-through sharpeners, honing steels and even most whetstones maintain or temporarily improve an edge, but they don't restore it. A pull-through sharpener removes material aggressively and unevenly, often shortening a knife's life. A steel realigns an edge but can't fix one that's genuinely dull. Professional sharpening re-establishes the correct bevel angle using the type of equipment knife manufacturers use to finish blades before they leave the factory: precision grinding wheels and tooling that costs thousands of dollars and makes no sense for a single household to own. The technique matters, but so do the tools: together, they produce a true, clean edge from heel to tip that lasts longer than typical at-home sharpening, and it's significantly better for the long-term condition of your knives.

It depends on how much you cook. For a household that cooks most nights, once a month keeps your knives in excellent condition. Frequent cooks, people who cook daily or prep large meals, tend to prefer biweekly. If you're not sure, monthly is a safe starting point and you can always adjust. One thing to know: the longer you wait between sharpenings, the more material has to be removed to restore the edge, which means slightly more wear on the knife over its lifetime. Regular maintenance is always better for the blade than occasional rescue sharpening.

They're sharpened overnight and back with you within 24–48 hours. In the meantime, on request, we leave a premium loaner set of quality blades at your door when we collect yours. Your cooking routine doesn't pause for a single meal.

Most standard kitchen knives: chef's knives, santokus, paring knives, bread knives, carving knives, single-bevel Japanese knives, and similar. We also sharpen scissors for an additional charge. We don't sharpen serrated knives (other than bread knives with a standard serration). If you're unsure about a specific knife, just ask when you book.

Yes. Every sharpening removes a small amount of metal, which is unavoidable. But professional equipment is calibrated to remove only what's necessary at precisely the right angle, minimizing material loss per session. Home methods, particularly pull-through sharpeners, tend to be far more aggressive and less precise, removing more metal for a worse result. Done correctly and at the right frequency, a quality knife will last decades of professional sharpening. What actually shortens a knife's life is infrequent sharpening using blunt-force home methods, or simply using a dull knife with excessive force.

Monthly is $29/mo (up to 6 knives, one visit per month), pick-up & drop-off included. Biweekly is $49/mo (up to 6 knives, two visits per month, billed as a single monthly charge), pick-up & drop-off included. A one-time visit is $39 (up to 6 knives): $29 for sharpening plus a $10 pick-up/drop-off fee. Plans are charged at booking; with code FIRSTFREE your first Monthly sharpening is $0. Subscriptions renew automatically each month. Extra knives beyond your plan limit are $10 each; scissors are $9. Nothing else.

Not a problem. Many of our customers leave their knives in a bag at the door or in an agreed spot. Just let us know in your booking notes. For drop-off, we'll place your returned knives at the same location and send you a notification. Once knives are left at your door, they're considered in your possession from that point, so make sure the spot is secure.

Yes, anytime before your pick-up through your account. No phone call needed, no fee. If you need to cancel a subscription, that's just as easy: cancel in your account and no further visits will be scheduled. We don't believe in locking people in.

In the rare event we cause damage during sharpening, we'll make it right, up to the fair market value of the knife, capped at $250 per item. Just flag it within 48 hours of delivery. We also photograph knives with visible pre-existing damage at pick-up, so there's no ambiguity about condition going in.
