1) Technical terms difficult to understand... and translate !
In the french language, several terms are used to talk about "knife sharpening". It is difficult to understand the difference between each words even for french people!
However, these different words are existing for a good reason : they describe several levels of blade maintenance.
We try below to translate these technical terms in order to help you to better understand our purpose. We hope we do not go wrong.
- - [FR : Aiguiser] - that we translate by Grinding: To create or recreate the cutting edge by removing steel in order to make the blade thinner.
- - [FR : Affûter] - that we translate by Sharpening: To maintain the sharpness of the knife so that it keeps a good cutting quality. Term often used in the common language for all that concerns the maintenance of the cutting edge.
- - [FR : Affiler] - that we translate by Honing or whetting : To make the cutting edge perfectly sharp. This must be done after use or after sharpening, by removing asperities created by the contact of the blade with food, a support or a sharpening tool.
2) When is it necessary to work on your blade ?
Before buying anything to maintain your blade's cutting edge, remember that you have to maintain your knife before it doesn't cut anymore.
There is not written rule on the subject but we can say that honing* must be made regularly, sharpening* often and grinding* the less possible !
