Years ago, when I lived in Seattle, I remember meeting an old Japanese blacksmith. I found him when I was looking to buy some of the pull-style hand saws, but when I met him to pick up the wares, it turned into a bit of a social call. He must've been around 80 or so, lived by himself in a house that was half home half workshop. Got into talking about saws and chisels and blades and sharpening, complete with a Mr.Miya…
Any tips to hold the angle steady?
do not believe other answer that says to just "practice" - you cannot hope to steady a blade with sub-millimeter precision, you must secure it...if you are off by a fraction of a mm you are resetting the edge
