I've had requests for touch-ups recently, each by new shavers, to make an edge more keen. In all but one, the blade sent is already doing an HHT 3 or 4 on a thick (.0033") wetted hair held 1/2" from the cutting point. Test shaves seem quite good already. Now certainly others may prefer a more crispy edge than I, and that's not hard to deliver, but I'm suspecting that there's something else happening that is being attributed to keenness.
Have any of you gotten this kind of request? How do you work the issue - just deliver nasty sharp? I'm inclined to probe for what action is occurring - what move is being made during the shave that makes them think more keenness is the answer. I'm suspecting technique - just from remembering my own (ongoing) learning curve.
