What It Is
With a precision sharpening system you sharpen kitchen knives, scissors and garden tools at home. Customers drop items off or mail them in and collect them sharp, and you can add regular restaurant or deli customers who send knives on a schedule.
The Pitch
Business Cortex says sharpeners at farmers markets charge about $6 to $10 per item, and describes one part-time sharpener who built 20 restaurant and store accounts visited monthly.
Who It’s Best For
Careful, hands-on people who like precise work and steady routines.
The Truth (as we see it)
The 20-account example involves visiting each business monthly, so the bigger version isn't fully home-based; drop-off work from home is the home version. Sharpening takes skill to avoid damaging expensive knives. Prices are modest, so volume matters.
