What tool is used for preparing woody parts for grafting?

The correct choice for preparing woody parts for grafting is a grafting tool. This specialized tool is designed specifically for making precise cuts and angles in plant tissue, which are crucial for successful grafting. The process of grafting involves joining two plant parts (the scion and the rootstock) so that they can grow together, and the grafting tool allows for the clean, precise cuts that help ensure a good union between the two parts.

While hedge shears, a half hatchet, and a hack saw can be used for various gardening and cutting tasks, they are not tailored for the specific requirements of grafting. Hedge shears are primarily used for trimming and shaping shrubs, a half hatchet for chopping or splitting, and a hack saw for cutting metal or plastic materials. These tools lack the precision and design necessary for creating the appropriate grafting surfaces on trees or shrubs, making the grafting tool the preferable choice for this particular horticultural technique.
