I have included photos of this hone with a worn out brand/logo. I don't understand how a recessed logo can get so worn. It seems that it's just a poor strike than failed to cut deep enough with a worn die into the stone. Can anyone give me some info. insofar as the brand , date and/or grit or anything? It's 5 1/2" x 2.0" x 3/8" Thx
