Thread: What does it indicate when your blade skips or catches on the surface of the stone?

It sounds to me like a wire-edge. Time to do some backwards strokes and strop it on stiff linen.
It is possible to wire-edge a part of the bevel and not others.
Setting the bevel on heavy grinds often takes longer to get the entire edge done.

If not completely set, one side or one spot will produce this sensation.
