My two cents.

A lot depends on technique. Watch carefully and follow your hand as you strop. Then follow the blade itself. How does the blade set on the strop before you start? Does your hand lift the blade slightly on edge as you finish a stroke or does it remain flat? Does the whole blade cross the leather with each stroke? Is each pass just like the last one? Do your strokes vary between each pass? Do you notice a negative difference in your razor when you rush the stropping? Do you give the strop too much give, is it too taut when you strop? Do you use quality leather? Is the leather supple or dried out?

Pastes on leather, in a way, turn a strop into a hone. Improper stropping can help create a concave in the blade and round out the tip on the razor with bad technique, add pastes to the strop and it quickens the damage.

IMHO,there is in no need of strop pastes, I do not know when abrasive pastes were invented, but if they were not needed 200 years ago, they are not needed today. The use of pastes may have been made for those who did not have quality hones, the paste served their purpose well and keep up a quality they were happy with. Heck, a lot of people use strops for their pocket knives and such, and they do not own a razor.

Not addressing and fixing ones consistent mistakes in stropping will lead to having to hone more often than would be needed.

I have not noticed a need to hone a blade often that was stropped properly. As we know, honing cuts the blade, too much or too often will shorten the life of a blade.

All this leads to the advice of having several blades in ones rotation. This will help preserve each razor.

Being methodical and observant will save a razor.
