Most straight razors seem to come from the factory without the toes being honed. Use magnification and you will generally see this problem. You can use the norton 4000 to get rid of them but it will take you awhile. I use a DMT 8E which is a continuous diamond extra fine 1200 grit stone. This will do the job quickly and leave a nice edge ready for a finishing stone such as the norton 4000 and then the 8000.
