The set
rip teeth filed straight across, cuts with the grain crosscut teeth filed to points, cuts across the grain set teeth bent alternately to clear the kerf stroke long, full, and let the saw do the work
Why not power
You can cut a beam with a chainsaw in a minute. You can cut a beam true with a beam saw — and the difference is what the frame shows.
