I got a set of Marples chisels based on word of mouth recommendation, opened the set, and was disappointed in the inital machining. It's taking forever to flatten the backs of these things, and I haven't started on the first bevel yet. I'm using a pretty new coarse poly diamond plate from Woodcraft, wet with a little water.
I guess my questions are: are the Marples always this poor to start with? And what can I do to speed up this flattening process? My hands are cramping big time.
TIA.
