Daily. Unless its my weekend and im too busy.
When i started with a straight it was every day. I found i had irritation often. Then i started shaving every two days. It helped a lot. I found shaving two days growth was much more satisfying and it was so much easier on my face.
Then about a year ago i deciede that my razors are so smooth now as my honing has gotten so much better, and the fact that ive learned how to properly shave, i started every day shaving. Unless im too busy. I enjoy it more and have no issues.
My wife thinks that my whiskers are growing faster. I couldnt agree but maybe. I am over 50 so i dont think its a case of puberty again. Lol.
