The Zenport professional small grafting tool is an excellent choice for making small, soft tissue grafts like tomatoes. Simply hold the tool and place the target plant to be grafted in line with the grafting blade. Press with the thumb to complete the angle cut. Repeat the step, and combine both upper and lower cuttings, securing the joint with grafting clips. Grafting tool keeps cuts at a consistent angle making combining the scion and rootstock easier. Please note: for use only with plants smaller than 9mm/.35-inch in diameter.
