Miter-Cut Grafting Knife

Works like an anvil pruner, with a razor blade on one side, and stem guide that serves as the anvil on the other. The stem guide channels align the stem before cutting. When the stem is in the channel, the blade is automatically mitered to the proper angle for making uniform cuts to ensure successful healing of the graft. Spring-loaded so it opens automatically after each cut. Includes three interchangeable stem guides: one with a 2.5 mm channel diameter, one with a 3.5 mm channel diameter, and one that is flat, as well as five replacement blades. Spare blades can also be used for side-grafting.
