Once the flat side of a cutter is flattened and polished it needs no further work other than regular backing off and stropping. If the strop is flexible at all then fine polishing takes place all the way to the cutting edge when both sides are worked.
Once the flat side of the cutter is flattened and polished, the time spent flattening and polishing it has already been wasted - that's the point!
I'm sorry to press you on this Charles - it's nothing personal. I agree entirely about the beneficial effects of a slightly deformable strop, it just frustrates and fascinates me that a straightforward, all upside, no downside, genuinely useful idea like the ruler trick meets anything other than instant universal adoption.
I have yet to speak to anyone who has a single
valid argument against it.
"Once I've wasted half an hour I can get the same effect as I could have achieved in less than a minute" still doesn't cut it for me.
