HOW TO GRIND PLUNGE LINES IN KNIFE MAKING
What is a plunge line?
A plunge line is the line where the bevel meets the ricasso. These are formed when grinding the bevel using a sanding belt, typically a 2" x 72" ceramic belt. Plunge lines can be straight, curved, smooth or sharp. In the video you can see the plunge line being ground down.

Step 2: make the spot where you want your plunge line to terminate / stop.
Step 3: work at the plunge line and work your way towards the tip.
