Sharpen knives, scissors and garden tools
Every kitchen has dull knives and every shed has blunt shears. A market stall or a weekly route through restaurants turns a skill into a habit people pay for.
- Who pays you
- Home cooks, gardeners and restaurants pay you per blade, in cash or by card at a market stall or on a weekly route, with restaurants often on a standing arrangement.
- Why this one
- Real skill, tiny setup, and the work walks up to your table. It stays pocket money, and that's fine; it's the most honest weekend on the list.
- Outcomes
- 0 receipts. Nobody's reported back on this one yet. Receipts open when accounts launch.
How it works
Sharpening is a skill most people don't have and don't want to learn, and dull knives are a constant low-grade annoyance. A sign at a farmers market ("Knife sharpening, while you shop") fills a Saturday morning. Restaurants have dozens of knives and no time; a weekly visit with a rolling case is a standing arrangement. Scissors, garden shears, mower blades and chisels widen the offer.
What it actually takes
- Whetstones and a strop, or a belt grinder for volume. Under a hundred for stones; a few hundred for a belt setup.
- Real skill. Practise on your own knives until they shave paper cleanly. Bad sharpening is worse than none.
- A stall fee or a route of restaurants and a case to carry things safely.
- Cut-resistant gloves and a first-aid kit. Obvious, but people skip it.
Where it goes wrong
- Damaging expensive knives. Japanese steel, serrated edges and ceramic need different handling. Learn before you accept them.
- Pricing per knife too low to cover the market fee.
- Overheating edges on a grinder. Slow and cool, or you've ruined the temper.
- Expecting growth. This is honest weekend money, capped by your hands.
