I have had that experiance with my new bismark shave but felt harsh even after belgiums but my other 15 razors were perfectly smooth i used ch.5 and it it was was worse i just kept repeating process bbw coti. i got my self a ch 12k did 100 passes on that and realy smooth now still don't no if ch12k sorted it but for the 14 pounds realy good hone. i also reckon i reset bevel and over did it this is why it could of been sharp but weak and harsh may be natural hones worked away the burr eventualy
