Shaving with a straight has become an addiction or rather a gateway. I now have purchased a few vintage razors from eBay and I plan to hone them. First one out was a smiley King Cutter that now shaves very well.
My question for the masses is how to avoid creating the smiley or frown when honing. Of the four razors I have purchased only the King Cutter was not a "straight" edge but I would like not to create a frown or smiley as I would hope to shave with the razors.

Any advice?
