Divided by cone angle accuracy
15 °/20 ° Small Cone Sharp Knife: The blade tip is extremely fine, specifically designed for small character carving, fine line carving, seals, and micro reliefs, with clear lines and smooth edges.
25 °/30 ° Medium taper Sharp Knife: The most versatile, balancing line accuracy and cutting efficiency, suitable for conventional text, pattern, and shallow relief processing.
35 °/45 ° large taper sharp knife: With high blade strength and large cutting volume, it is used for integrated operations of deep relief, large surface material removal, and rough and fine machining.
Divided by the shape of the blade tip
Sharp edged knife: No flat bottom, sharp edged, suitable for sharp edged contours, fine line edges, and fine engraving.
Micro flat bottomed sharp knife: The blade tip has a small flat bottom (0.1-2.0mm), and the processing bottom surface is flat, suitable for relief bottom surface cleaning and slotting processing.
Divided by handle specifications
3.175mm knife handle: universal for small precision carving machines, suitable for processing small characters and fine molds.
4mm/6mm handle: More rigid, suitable for medium and large carving machines, with better stability, suitable for batch and deep carving operations.
Divided by material and structure
Solid hard alloy (tungsten steel) sharp blade: high hardness, wear resistance, and stable accuracy, making it the mainstream for high-speed precision machining.
Extended blade straight groove sharp knife: With a longer blade length, it is used for scenes such as deep cavities and high reliefs that require deeper cutting.
