I think I read somewhere that a line drawn with a marking knife would actually cut the fibres of the wood - is that wrong or correct? Cheers RobynThe trick is to start a cut by pulling the saw back for a stroke or three, from the back of the workpiece, until there's a big enough kerf to take forward strokes.
The bigger the tooth the longer the starter back strokes required - you need 2 or 3 teeth minimum in the kerf to cut forward easily.
You would really notice this with e.g. a 4tpi rip saw - very difficult to start on a forward stroke
