So the wife asked the question.

Having experience in this..The hardest areas are the feet, ankle, and knee areas. You have to be the most careful there. Also, I find that to complete one total leg shave, of all areas on the legs and all the directions, it takes a ton of soap or cream. I would recommend a hard soap that you just keep reloading and reloading. It'll take way more lather to do legs than your face. You just have to be careful, just like with your face.
