The scion is typically the top part of the grafted plant. If it is inserted lower down on the plant during the grafting process, everything above the scion is usually cut off in the spring. This forces all of the nutrients and water from the rootstock into the growing scion.

Grafting saw blade is 6mm and 4mm kerf which produces a 6mm or a 4mm groore in root stock to take a prepared graft scion stock.
