What it is

A website selling a focused range, such as kitchen knives for home cooks, plus a sharpening service where customers post their knives to you. You work from a spare room or garage.

Your first three steps

  1. Choose a niche (for example Japanese kitchen knives) and approach a few UK suppliers about trade accounts
  2. Practise sharpening on whetstones until you get consistent results, and set a price per knife
  3. Build a simple online shop with age checks at checkout and a clear postal sharpening page
Who pays

Home cooks, keen food lovers, gift buyers and small food businesses who want quality knives kept sharp.

How it makes money

Profit on each knife sold, plus a fee per knife sharpened. Sharpening brings repeat customers and often leads to new knife sales.
