Sorry Philip I didn't realise it was you in the Utube clip and was trying to be light hearted - obviously a mistake. I have removed the offending messages.
For the stabby action - when I learned dressmaking we learned to cut our material smoothly and I shear the same way. Every shearer chooses the way they shear to suit their own preference - my back is older than yours so I do it my way, but there is no reason for you to be offended by that.
