Brand new razor = factory edge
I do not consider a factory edge to be shave ready. I hear your kind of story all the time from people! The new razor needs to be finish honed and stropped. I also recommend you leave your stubble long and not pre-shave with an electric. Consider that you may not be doing anything wrong so much as just not doing the right things yet! Give me a call during the week 8am - 5pm eastern at 508-842-7132 if you want me to talk you through all this. Don't give up! Shaving this way is just another skill to acquire.
