I came accross this on ebay :
Attachment 175480
The instructions say to strop 2 or 3 times on leather ! I also have a few old instructions that appear on boxes and allot suggest very minimal stropping, the most i have seen i think was 6 passes.
It has got me thinking if our 80-100 passes is way over the top?
It may very well be a case of YMMV but i was wondering where the increased number suggested today came from and why in the olden days the number of strokes suggested is way way less :)
