Sharpening is a physical process which requires all of our attention. I have always said to my students is that you need to push the tool down hard onto the abrasive. This is all a bit subjective until we start measuring and this is what this video is about. I am using up to 6 kg of pressure when sharpening my scandi ground carving knives. I using the same amount of pressure when stropping and then ease up for the finishing strokes.
The one thing I did not mention in the video is that when learning sharpening do not go in hard straight away. Start light and make sure that abrasion is taking place in the correct places along the bevel of the knife. Go in hard get the angles wrong and you have created a secondary bevel and a lot more work for yourself.
