The MOST important tool that everybody doesn’t know or forgets about in wood working is wax/oil/paste wax. This is because you use this to lubricate the faces of your tools, what slides and presses against the wood. Just by applying this to the sole of your plane makes it 2x easier to push and is a game changer.

You can add this to your saws as well and they will glide through their cuts with ease. You can put it on a shooting board too, anything that your tools rub up against.

Another good one is saw setting pliers. These exist to easily adjust the “set” of a saw. The saw’s teeth taper out slightly to make the width of the cut wider than the saw plate, to prevent binding in the cut.

Cheaply made saws often have a poorly made set, often far too thick which makes a very wide cut (the saw is now more likely to wander off cut) and slows you down significantly. If the set is 30% wider than it needs to be, the saw is now by extension 30% slower (you are removing more material than necessary).

Now to the point (no pun intended). The biggest difference in performance from a cheap saw and expensive saw IS the set, and with these pliers and a triangular file you can make every cheap crappy saw cut like a dream and just as well as any expensive saw. Only thing other than that is the handle, which you can carve down yourself as most are too large.
