Knife Sharpening Route
The world's oldest B2B subscription: sharp knives, forever.
Bottom line
Strong cash-flow candidate with manageable operations.
Commercial knife sharpening businesses service restaurants, butcher shops, hotels, catering companies, and food processors on weekly or bi-weekly routes. Each stop takes 15–30 minutes; clients pay $50–$300 per visit depending on volume. A solo operator servicing 30 accounts can generate $120K–$180K/year with 50–60% profit margins — working 4 days a week. No digital disruption possible. Restaurants always need sharp knives.
How It Works
Operators run scheduled routes to commercial kitchen accounts. They pick up dull knives, sharpen them on-site or at a mobile unit, and return them same-day or next visit. Pricing is per-knife ($3–$8 per blade), per-set, or flat monthly retainer. Equipment is a sharpening system ($2K–$8K) plus a vehicle. Accounts are stickier than almost any service business — chefs don't switch unless something goes wrong.
