Losing tip on Sharpmaker

May 31, 1999
For some reason, I've lost the tips on my Calypso Jr. and AFCK using the Sharpmaker. My Calypso's is seriously GONE (read: very blunt). Is this a inherent problem with the rig, or am I not using it properly? Thanks.

That is a very easy thing to do. The cause is the rotation of the knife as you execute your sharpening stroke. As you sharpen the tip, you don't want to stroke past perpendicular to the edge right at the tip. The result of doing so is the same as if you held your knife tip first onto a grinding wheel. The tip will eventually be ground square.

As your sharpening stroke nears the tip, make sure that the blade is still more or less level. You will want to rotate the tip downward slightly to keep the angle consistent, but the trick is not to rotate too far. The ideal is to keep the edge perpendicular to the stroke, but it is better to rotate to little than to flatten the tip.

I learned this one the hard way.

Hope this makes sense. It is a tricky one to put in words.

Thank you for your replies, I'll start working on that

This isn't apt to be a problem if one simply uses a stone without the miracle attachments.

I investigated the loss of the tip on my Endura and came to the conclusion that I was using the sharp edge of the stones to much. This resulted in the tip sliding down the flat edge of the stone at the end of the stroke at a very acute angle.
Yes, it is possible to round of the tip using conventional flat stones, so Desert Rat's answer could be an oversimplification, depending on the technique that is used. The solution is to not drag the tip all the way off the rod, or past the edge of a conventional flat stone. Sharpen on the flat sides of the Sharpmaker triangles, and stop your stroke while the tip of the blade is still on the sharpener.
