It's not difficult just expensive for one knife blade. It is an industrial process, Stone washing is done in a huge drum where parts are tumbled with "stones" and a soapy water soloution. The stones are really chunks of ceramic in different sizes and shapes. The process is commonly used in the auto industry to remove burrs from parts.Originally Posted by dulaboy
You could try rubbing out the blade with a scotchbrite pad. You could try tumbling it yourself with a coffee can and some shiney pea gravel and soapy water? Roll it back and fourth on the floor for a few hours. No
way to guarantee you will get the result you want though!
