This hand-held, manual grafting tool is very easy to use and can do grafts on plants up to 13mm in diameter. It makes an "Omega" shape cut which creates a tight graft. Hold the stem of the stock plant in the grafting tool and squeeze the handle to make the cut. Repeat this step to get a piece of grafting stock from the donor plant. Take care to ensure the "groove" is cut into the stock plant. Once you have joined the 2 pieces of plant material wind a piece of budding and grafting tape around the join to ensure a successful graft. The front of the tool has light duty pruning blades that enable the user to cut off any useless branches or leaves.
