I noticed in the barbers manual in the archive that a "smile" should be put on the blade, ideally.

I have finally managed to perfect my honing to get a good edge on my new bengal, however I initially practiced my honing on an ebay cheapo that actually has a "frown". Meaning that the width in the middle of the blade is less than at the toe and heel. As this razor has a frown it is very diffilut to hone it evenly.

When doing the x pattern type of honing, the heel and the toe spend less time on the hone than the middle and thus a frown may be developed as it will wear more in the middle. I do not want this to happen to my bengal. How do you prevent or correct this?
