Planing & Cutting Back Side Walls
While sharpening and polishing side edges and in order to cut the metal side edge only, the sidewall material needs to be planed or back-filed. Otherwise the cutting tool will get clogged with the sidewall material and reduce the efficiency and possibly the accuracy of the desired bevel.
A Sidewall Planer with a carbide blade or bit will remove a nice, clean fillet along the edge which can be further sanded to smooth out any irregularities and provide a smooth surface.
Here’s a clip from the SVST Tuning & Waxing DVD on Side Wall Planing:
Many Multi-sjde edge tools like the Tools4Boards Razor or Xact work very well as multi-angled tools when set from 5° to 6°. So do dedicated edge guides of 5°/85°/95° to 7°/83°/97°.
