I'm not a pro - still got a lot to learn. I am burning what I grew, so that's something!
What I done was stripped the bottom 1/3 of the stem! Really hurt until I put them in flower, about a 10 days later.
I left maybe eighth to a quarter inch below my cut. I tried to make 90* cuts for a smaller wound. Be sure to clean your blade/scissors with alcohol before starting. Any branch 2-4 inches long will make clones. Cloning isn't as hard as you may think. A lot of ways so a lot of onfo, pick one & go for it! I had real good success from a bubble cloner - search for diy $20 cloner. It's made from a coffee can & it works.
