During the sharpening process, if tools (such as kitchen knives, scissors, plane knives, drill bits, etc.) lack fixation, they can easily shift due to uneven hand pressure or machine vibration, resulting in uneven wear on the cutting edge or even breakage. The support frame securely fixes the tool in the preset position through slots, clamps, or magnetic attraction, preventing any movement. Support frame height: 120mm (JT – 20), 200mm (JT – 50)
