Video showing Harry Harrington of Bonsai4me.com carving an old yamadori Hawthorn collected by Sean Stolp.
The 77cm/30" tall tree had poor taper in the middle section of the trunk and in this video, the area is carved to improve the taper, and hide the large trunkchop.
Carving tools, including Bonsai Nibblers, are available from the Bonsai4me.com/shop
