For those that haven't heard of the whip and tongue graft, it is a very common graft that has two beneficial features: good surface area contact and also strength from the tongue part of the graft that holds the two pieces of wood together tightly.

I've seen most whip and tongue grafts done with a grafting knife, but haven't seen anything on using a pruner for the diagonal cut, but still using the pruning knife for creating the tongue.
I would think that it would greatly increase the speed that these grafts could be done and also make it easier to create matching cuts to join the two pieces.
Has anyone used a regular pruner for whip and tongue grafts?
