BEFORE YOU START
The amount of time required will vary when a knife is sharpened for the first
time with the , depending on the condition of the blade and
the quality of the steel. The edge must first acquire the chosen 15° or 20°
grinding angle. However, thanks to the constant grinding angle, only a
few rolls back and forth are needed for subsequent resharpening.
When a diamond grinding disc is used for the very first time, some
excess diamond particles are eliminated. This is audible, but quite normal
and occurs only once. After a few minutes, grinding will become quieter
and the grinding disc’s surface much finer. The grit of the disc should now
be only slightly rough to the bare finger. The disc has reached its working
surface condition.
The marker pen method
Use the marker pen method to visually check the success of the grinding process.
Carefully draw the felt tip of a marker pen along the entire knife edge, so that it
simultaneously leaves ink on both sides. Once the ink is removed by grinding on
both sides, the desired angle is achieved. horl.com/faq
