The double-edged straight groove flat bottom sharp blade adopts a dual cutting edge and straight groove chip removal structure, and the blade head is in the shape of a flat bottom sharp angle. The double-edged design has stronger rigidity, smoother cutting, less vibration during processing, and is less prone to tool breakage, making it suitable for materials with higher hardness. The straight groove has smooth chip removal and is less prone to clogging and sticking to the blade, resulting in higher efficiency than a single blade. Flat bottomed sharp corners can be carved with clear edges, sharp lines, and fine text patterns, with neat cutting surfaces and distinct edges. Mainly used for fine carving, edging, engraving, and corner cleaning of materials such as density boards, solid wood, and hard plastics, balancing rigidity and accuracy, with a wide range of applications and strong practicality.
