I have seen plenty of smilers for sale here and on other sites like the bay but they have all been vintage (I have 2).

Were/are smilers made deliberately or accidentally by honing?

I haven't actually seen brand new purposely manufactured smilers (except for custom jobs) but maybe I am just looking in the wrong places

As an aside, I have read that a lot of people like them. I think I actually prefer straight blades. Every time I use a smiler I seem to end up with red scratches on the side if my neck. No blood but scratched enough so the marks last a couple of days.
