W1: The width of the front end of the cutting edge of the tool is commonly 2MM or 1.5MM. It is generally set slightly smaller because one end of the front end is ground to facilitate chip removal, resulting in a slightly smaller actual width.



H1: The length of the cutting edge of the tool should be lower than the height of the material being cut. Generally, H1 should be set to around 5MM.



Carvable materials: two-color board, PVC board, organic glass, ABS board, etc.



Cutting materials: two-color board, ABS board.



Therefore, this type of cutting tool is mostly used for carving large characters on department signs, also known as department sign knives, but the carving effect is slightly inferior to flat bottomed pointed knives of the same width. The edge of the material it cuts is straight, while the edge of the material cut by the flat bottomed sharp knife has a slanted edge, and the degree of inclination depends on the angle of the tool. The larger the angle, the greater the edge inclination.
