i was disappointed in that geo fat boy video or dovo. i think any razor can shave sideburns which he only does in video. the chin tells me if it's shaving sharp and smooth. I don't agree that these blades out of the box can't be improved by even a horrible honer like myself. If one thinks that the blade out of the box is the best that it can be, then we're going to lose people back to double edge or multi cartridge.
