For a daily use straight razor, about once a season or twice a year.

Remember that you keep a razor sharp by using the pasted strop and having a good maintenance routine. After a while the cutting edge becomes more convex, which is where the stone is needed to straighten out.

A coticule is flattened on every use, because you rub a smaller stone on it to create the milky suspension that will do the actual abrading. I've had the same stone for 20 years.

That has not been my experience with stripes. Things got way better once I did a quick pass On an "Arkansas" stone before each use, but I still need to use something coarser once a month or so.
