stocks can be cut off with a strong, sharp knife, but if 

 too large to be cut in this manner, a fine sharp saw 

 is used, and the top of the stock smoothed over with a 

 knife. A split is then made in the stock an inch or

A number of different implements have been invented,

The scion, which should be well ripened wood of last

 The stock is then opened with some kind of a wedge
