This Electric Hand-Held Twist-Tie Tool is designed specifically for use in agriculture and can help reduce the risk of carpel tunnel or repetitive motion-related injury. Unlike stationary twist-tie machines, it can be taken in the fields to stake agricultural products and vines, such as tomatoes and grapes. It reportedly delivers 8 hours of continuous tying per battery charge. The tool comes with three 656-foot rolls of brown twist tie (each producing 1430 51/2-inch ties), plus corded charging unit. Reportedly able to tie up to 1-inch-diameter plants, it has an extended front-tying aperture and tightness/looseness of tie is adjustable to minimize potential damage to stem or vine as the plant grows.
