Grinding an Onglette graver


This initial preparation consists of removing the “Tang”. Then having it be inserted into the wooden handle of your choice.
Lighting above the bench-grinder is very important as you must see any subtle changes in the shaping of the Onglette blade.
The next very important stage is to accurately shape the front part of the blade to a fine point.
Water immersion is very important, if the blade overheats it will turn a bluish colour & have the steel soften.
I use a ratio of three grindings to one of water. In my next video will show how the finished blade will look.
There are many ‘delicate steps of preparation’ before the actual “Bright-Cutting”. One thing to remember, there are no ‘short-cuts’..only doing things the correct way!
