Anyone ever hear of this? Is it an effective hone, to your knowledge? I know NOTHING about honing/hones. I'm a DE user myself. I won a vintage brush and straight razor combo on eBay and the seller threw this in at no cost.
(The straight razor I got with it is marked Griffon and looks like a 4/8 to me)
