W1: The width of the front end of the cutting edge is commonly found to be 2MM or 1.5mm. Generally, it is set slightly smaller because one end of the front end is for the convenience of chip removal, and one side of the edge is polished, so the actual width is slightly smaller.
H1: The length of the cutting edge of the tool, the height of the material being cut should be lower than the length of the edge. Generally, H1 should be set to around 5mm.
Carvable material: dual color board, PVC board, organic glass, ABS board, etc.
Cutting material: dual color board, ABS board.
Therefore, this type of tool is mostly used for carving large characters on department signs, so it is also known as department sign knives, but the carving effect is slightly inferior to flat bottomed pointed knives of the same width. The material edge it cuts is a straight edge, while the material edge cut by a flat bottomed sharp knife has an additional slanted edge, and the degree of inclination depends on the angle of the tool. The larger the angle, the greater the inclination of the edge.
