The perforated hone co.

So today I picked this up for $10 at an antique store along with another King cutter I paid $30 for. When I saw it I thought it was really cool. Its called the Hone your own razor hone. Its about 3 1/2" x 2" and has dimples like a golf ball on one side. It says its to get rid of the wire edge on the razor. Its definitely been used quite a bit as both sides are dished. I dont think ill be using this one as a finisher but it will go in the display case. Says it was made in Walkerville, Ontario, Canada. The patent on it is U.S. March 1910 Pat. Canada, Great Britain, Australia, New Zealand. What do you guys think???
