Coping/Fret saw
Keep tilted backwards, use the entirety of the blade, smooth, regular strokes. Do not tilt too much side to side, but keep tilted backwards.
Tenon Saw
Focus more on getting the cut in the right place – the weight will direct the saw for you, all you need to do is pull backwards and forwards in the right places and it will cut.
Large Saw
Keep it low, keep it at 90 degrees. If it’s not cutting effortlessly, you’re going wrong or the saw isn’t sharp enough.
