This root and sod cutter works very well in removing bonsai from the pot and then sawing away tightly packed soil and roots. I could not be without one myself. Especially good when you buy a pot bound tree that needs large amounts of soil and roots removed. This tool has many applications around the garden and your bonsai tool roll should not be without one, especially for the price. 4 1/4" blade, 9 1/2" overall
