The Vinity Straight Razor or "shavette" option means that it uses replacement blades. There is no stropping or honing required so you save cost and time in maintenance. Just invest in some inexpensive blades and you are good to go. It takes 1/2 of a double edge blade inserted into the holder (blades not included) . So you can have a fresh edge whenever you want. This is great for those who want the sharpest shave every time, or professionals who need to change out blades between customers.
