Universal attachment for the convex edge.

The TSPROF provides the attachment for convex sharpening of blades as a removable adapter, which is easily mounted on the abrasive holder. These adapters provide a uniform change of the angles across the entire width of intake, and the result is the lenticular shape.

The convex sharpening of blades proved itself very well under shock loads, during cutting of reeds, coastal shrubs and grass, large raw bones, keratinized branches, it is significantly more effective for deep cutting compared to blades with V-shaped sharpening, provided that the blade is of a similar thickness. The reason is less 'sticking' to the material. This form is most suitable for military weapons with long blades, large knives, logging axes.

Angle ranges (radius) are determined by the position of the rod in the attachment. The attachment is marked with the appropriate range (radius). 

To select the range (radius), you have to focus on the thickness behind the edge of the blade. With a minimum thickness of 0.2 - 0.4 mm, attacchment of 4.3 degrees is suitable; with an average thickness of 0.4 - 0.6 mm, attachment of 7.2 degrees; with a thickness behind the edge of 0.7 mm, attachment of 10.7 degrees is suitable.


Set includes:

  • Three radius adapter (4.3 °, 7.2 °, 10.7 °)
  • Titanium guide rod
  • Bushing adapter
  • Installation kit

Attention! This attachment is only suitable for TSPROF K03 and K03 sharpeners. To create a convex grind using TSPROF Kadet or Blitz, you should purchase TSPROF Convex Mini attachment.
