Ken, Sorry late reply. A knife in constant use in a boning room for instance, would be a daily sharpen if you have not hit a chain mail glove or such. A worker would normally carry two knives and steel which normally gets them through the day. For sharpening we usually look for thinness behind the edge to stop the wedging effect which causes drag, a knife will shave but still drag if to thick behind the edge. The sharpness is not determined so much by the grit of the stone as the last thing to touch edge determines sharpness, in our case it is the steel which determines sharpness, as such the knife needs to be able to shave after steeling. Workers would probably make three thousand cuts a day, steeling is vital to maintaining an edge throughout the day, a good steel is treasured.
As an example: Using a norton india fine bench stone to finish edge, and steeling. Using a victorinox six inch curved boning knife we could easily bone twenty beef bodies daily, or one hundred and twenty sheep which was a normal days work.Understanding steeling is very difficult to teach, there are many misunderstanding about their use which can only be gained with experience. I have not worked in the industry for twenty years and know that much has changed. Brinky
