The handsaw is used less these days than before power tools but still a lot.
The handsaw is used less these days than before power tools but still a lot. 'Let the saw do the cutting' means exactly that. If you are getting tired wrists or sore hands when using a hand saw you are pushing/trying too hard and more likely to wander off course. Keep your index finger pointed down the length of the blade to help keep it stable and apply the minimum amount of pressure.
