If the blade is stroked against the stone at different angle, the sharpening process will fail.
But it is difficult to learn to make the strokes consisten and correct t without some guide.
This instructable shows how to easily make that sharpening stroke consistent and the sharpening process successful.
The device made in this demo will help the sharpener keep the angle consistent.
Step 1: Materials
Two scrap pieces of wood, each about 6 " X 6" X 1"
The two pieces must have the same width and thickness , but may be different lengths.
Plywood is good because it resists splitting
1 Double Sided honing/shrapening/whet stone at least 6" long by 2 " wide ( cost about $12)
3 2 " screws
