Start the saw without the blade for a split second to see which direction it spins. The saw blade teeth should point in the same direction. The points of the teeth are the part that should strike the wood first.

The teeth on the bottom cut into the wood.

Holding one in front of you they go clockwise looking from the right.

The blade is places so teeth cut on the push stroke.
A chainsaw's chain should be fitted so that the points of the teeth face in the same direction as the chain moves. Then they will cut into the wood without needing much downward pressure. If the teeth are sharp you should never have to force the chain down into the surface of the wood. If you find you have to force the chain down to make it cut the wood then the teeth must either have gone blunt - and the chain needs to be sharpened or replaced - or the chain was installed with the teeth facing the wrong way so that the backs of the teeth just rub over the surface of the wood and you need to press down very hard just to get the teeth to wear down into the wood instead of cutting it cleanly.
They both resemble your mouth, in that all three have teeth.
It could be a way to get your attention or it could be a way of them filing down their teeth.

Most blades anymore are marked which end goes towards the handle. If not, the points on the teeth should point away from the handle so that they cut on the forward stroke.

It doesn't matter on a diamond blade. Either way will work. Usually there is printing on one face that would face out, on the nut side, but it doesn't matter.
There is no definite date on that, but tenon saws have been used for at least 200 years just the way we see them now.
Initially created by wood land farmers. It was a way of cutting down to size trees that had been harvested. From there a range of versions came on to the market.
