There are number of ways to squeeze a lemon. Some of them are:

I have seen a few modern tools on various websites. It is so easy to get convinced into buying these.

Some people even suggest warming up the lemon or rolling it on a flat surface before squeezing it.
But the best method that I have found is sticking a fork in half a cut lemon and twisting it. It is easy and works every time. This saves time spent in cleaning tools later.
