The problem with barber's hones is they are very small and can be tricky to use. There's a good reason the old barbers put smiling edges on their blades, the barber hones are much easier to use on smiling edges. My King barber hone puts an absolutely wicked edge on my smiling blades, but it's a good way for me to dull my straight edged razors.
Aren't eschers and coticules typically pretty small as well?

(Thanks for your good advice the other night mparker, that did the trick both for the hone and the razor.)
