How are you sharpening your HSS and masonry drill bits

There's a knack to it and once you get that, it's a breeze. 2 parts to it - 1st is the cutting edge and 2nd is blending in the face (HSS bits) Here's a still from a vid I made to explain - I've put a good edge on it and the face now needs to be blended - That is a freehand wiping up motion to get rid of that line you can see in the middle of the face
The lines on the tool rest are scribed into it at 59 degrees (half of the 118 degrees mentioned in the op's vid) and that's the angle you rest the bit at to get the edge sharpened - I can do any size down to about 3mm (below that, it's hit n miss)
