How to make straight cut

In woodworking, cutting is the most essential and fundamental step. Beginners might struggle a lot in how to make straight cut.
Today, we will introduce some tips on making straight cuts using saws.

1. draw lines on all four surfaces.

Use a straight ruler and a pencil to draw a line around the wood surface. 
Be aware not to use mechanical pencils, because it may damage the wood surface.

Although not necessary, sometimes we use carpenter's square (ruler with a right angle) to draw lines around the wood surface. (but this is not recommended for beginners because sometimes you may find that the lines cannot get connected)

Which part on wood exactly should we cut?
After drawing line, but along which part should we cut?
The answer is, we should cut along the outer side of the wood. Think about it, if we cut above the line, there would be wood scraps, so the actual size will be smaller.

2. fix the wood
When actually cutting the wood, it is important to fix the wood well.
Sometimes we fix the wood by the clamp. 
Especially if the size of wood is small, it can be cut without using a clamp. It is instead inefficient to fix it in every cut.

3. watch the wood carefully

It is easily imagined that people usually fix the wood by stepping on it, and cut wood by pulling the saw from the bottom.
Since Japanese saws cut by pulling, we need to step firmly on the wood to fix the wood.
However, in this way, we cannot make a straight cut.
The reason is, when you step onto the wood, the lines drawn will be far from your eyes.
So those lines will be meaningless.

Therefore, we need to put the wood on the table.
However, if we want to cut like this way since Japanese saws cut by pulling, the wood would have the tendency to be lifted up, so hands will exert extra force to fix it.
In this way, hands will get tired, and will easily shiver, and will be harder to make straight cuts.

The correct way of cutting is like this:


Use left hand to lightly hold the wood, and cut as if cutting vegetables.
Pull the saw diagonally from upward to downward. In this way, the wood gets downward pressure.
This is why you only need to lightly hold the left hand.

4. Cut the wood while rotating
If you cut the wood while rotating, grooves will be made.
Then you can just cut along the groove.
This is the purpose of the lines drawn in step 1.

There is another benefit of rotating.
If we don't rotate the wood, the cutoff part of the wood will crack like this.

5. Use all saw blades to cut
If you only use a small portion of a saw and keep pulling repeatedly, you will only get tired, but the efficiency is low.
Therefore, it is important to use the whole saw blade when cutting.

I hope all the above can help you in making straight cuts!!
