SKU TS-PT2200330


• Works with K03 Pro (only).
• 3 convex offset ranges: 4.3°, 7.2°, 10.7°.
• Convex grind is the best for impact loads and heavy work. • This geometry makes the blade stronger, because it has more material near the edge.

Works with К03 Pro and К03 Lite.

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.

The set includes:

  • Convex Pro attachment with three angle ranges: 4.3°, 7.2°, 10.7°;
  • M4X6 fixing screw 

Not suitable for older K03 sharpeners!

Convex Attachment review

First, I would like to say, that the K03 is my first experience with a guided sharpener of any kind. I have used the convex attachment twice so far. The only issue that I have encountered is that it has a tendency to turn slightly during use, thus changing the sharpening angle ever so slightly. I now have been watching and adjusting this carefully during use. Perhaps I am not tightening the attachment firmly enough? Aside from that, I find the K03 to be beautifully machined, and precise.
