I figured this would be an excellent place to obtain information on how you all make your cuts on scions. I graft mainly avocados....but I am thinking that my method is really a left-handed (backwards) method. I was always taught to cut with a knife away from my body. Is this wrong? As I consider a grafting knife purchase....I am thinking the standard flat edge on the blade...may be on the wrong side for me. What is correct???
