OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scott Bonnar blades

Hi again. Had my 14 inch sharpened a couple if weeks ago at a local mower shop. At the same time they replaced the bottom blade.
In my opinion the roller doesn't seem to be very sharp. How sharp should it be? Should it be capable of cutting my finger like a knife would?
Should the bottom blade have any sort of edge ground on it ?
Cheers Tony.
