TSPROF K03 Pro convex attachment is a special attachment that affects the movements of the guide rod and allows you to sharpen and create convex blade grinds. Works with К03 Pro, К03 Lite, K4 sharpeners. Not suitable for older K03 sharpeners! Fixed angle convex attachment Use the attachment on the abrasive holder to create a convex grind. The attachment provides a uniform angle change across the entire width of the secondary bevel. Angle Range: 4.3°, 7.2°, 10.7° As the abrasive moves along the secondary bevel from the cutting edge line to the knife's spine, the angle range changes in the direction of decreasing the angle. The angle range scale is printed on the side of the attachment's body. You have to match the angle hole according to the thickness behind the edge (TBE) of the knife: For TBE of 0.2 - 0.4 mm, use the 4.3 degree hole; For TBE of 0.4 - 0.6 mm, the 7.2 degree hole; For TBE of 0.7 mm or more, the 10.7 degree hole. Set includes Convex Pro attachment with three angle ranges: 4.3°, 7.2°, 10.7°; M4X6 fixing screw
