AQ：This is the way to get better at sharpening plane blades.
There is something to keep in mind when adjusting a blade or the base.
When using a whetstone to sharpen a blade, including plane blades and chisel blades, when you are moving the blade only apply force in one direction.
Firmly apply force when pushing forward, and relax when pulling back.
Apply force going forward, and relax going back.
This is because how you apply pressure going forward is always different than the pressure going back.
Same thing when sharpening this ridge, or using this metal plate to clean the back side.
Determine the direction, only apply pressure in that direction,
and keep it stable to sharpen and shape the blade.
