This precision triangular knife is used for cutting plastics with a pin vice.
By pressing the blade at a constant angle, you can smoothly carve grooves of the same depth.
The width of the cut varies depending on the angle of the blade, so you can use it according to your purpose.

This set of 4 comes in angle sizes of 5°, 20°, 45°, and 90°.
The shafts are all 3mm, so there is no need to replace the collet chuck on the pin vise body, making it easy to replace.
*As this is a blade, please handle it with care when opening the lid or using it.
