Thanked: 2209Hello all
It has been some time since I last posted on a thread. For that I apologize.
Regarding this thread .......
I read Iwasaki stuff long ago and have since watched the above mentioned video.
Based on my limited experience I never do jointing when restoring an old/damaged/oxidized edge. By jointing am referring to using a 90 degree angle. The reason is that it creates a flat edge that simply requires more work than is necessary. What I do in that case is to use a 30-45 degree angle with pressure to rapidly remove the nicks/chips/old rotten soft steel. From there I go to the 1000 grit to establish the bevel. It is much less work and has the same effect.
I do not use either the jointing or 30-45 degree angle ever again during honing. What I do use instead are 10-20 back honing (spine leading) strokes followed by 5-10 normal edge leading strokes. Normally this will be beneficial after the 1K & 4K because this is when a wire edge/burr might form. I will also use the back honing stroke as a precaution on the higher grit stones. Sometimes it is beneficial and sometimes not.
So for me, based on my personal experience, jointing is a waste of time, there are better methods.Last edited by randydance062449; 12-12-2016 at 09:16 PM.
