Osiyo,
You dont have to use a saw at all to put self nocks in cane . Get a sharp knife,hold it at a 45 degree angle at about 3/4 of an inch from the end where you want a nock,now cut using strokes going away from your body. Now rotate it 180 degrees and do the same thing. Then i use a thin folded piece of 80 grit sand paper to sand out the center. Thats all there is to it. I cut my slots for the arrowhead the same way. If you have question pm me.
