It's been a while since I used a straight razor. I used the one that has changeable blades and I used Derby razor blades. You know how everyone says "let the razor do the work" when I use the razor I have to give it some force in order to cut the hair. I use Proraso shaving cream and a Badger hair brush, but when I shave the razor doesn't run as smoothly as I see on all these videos on YouTube. It looks so effortless, but when I do it, you can see i'm using some effort. The blades I use are new. Is a regular straight razor sharper than a changeable blade razor?
