Hi, I teach in a secondary school, when I was a pupil, and when I was at teacher training the waste wood from a cross-halving would be removed with a bevel edged chisel flat side up; making a small "hill", the chisel would only be turned flat side down for the final paring. A new guy fresh from collage has arrived this week and upset the cart. His college said flat side down, all the time. The reason I was given was to stop the chisel digging in beyond the line, which has happened when students put the flat side down. Whats your thoughts? An up or down answer is enough.
