Final leather paring.
The leather is creased and given a memory along the joints with gentle strikes with a hammer.
Then the joint area of the spine is pared down ... not to much as we still want to keep the strength but allow for flexing.
Then more paring at the head and tail of the spine area, this is to allow for the leather that turns in... basically to keep the spine as smooth as possible.
The final cut... a single cut to scollop and feather the turn-in at the head and tail. All simple and not a spoke shave in sight.
