Well as usual Lynn's posts are the shortest around here but he says more in them than most guys who go on for a page. I would take his advice.

I do think 50x on linen is way too much. On leather you can hone to your hearts contentment I don't think its possible to overhone on smooth leather (well maybe if you do 1000 strokes) but 30, 60 80 -no problem.

What concerns me more is that the razor seems to shave fine at first and then losses its edge midway through shaving. Usually sharp is sharp unless you really don't know what sharp is and you are actually shaving with a marginally sharp razor and its just deteriorating as you shave.

Let us know what happens.
