Machinist's Ruler?
Is there a consensus among Ye Great and Famous Honers as to whether the flatness of a hone can effectively be checked by placing a known-quantity straightedge against the surface, and looking for any light that's leaking underneath? If a hone should pass that test, would some folks lap it all the same, just to be sure?
many thanks...
