They are very good barber hones and prices have been creeping up on them as they are not as abundant as say a swaty and other nice barber hones. There are some smaller frictionites out there called "Little frictionite" and are about an inch shorter than a normal sized barber hone. They normally a combination of finishing on one side and a little coarser on the other.

I find that a Swaty can do just as good and are priced reasonably. In any event frictionites turn up now and then, good hunting.
