This mod adds 6 sickles to minecraft. In the picture from left to right they are:
A sickle in this mod will attack at the same speed as a sword. But the thing is that they deal more damage. Sickles besides being good weapons are reasonably good at breaking wooden objects. With this mod I am sure that when you start a new survival world you will make a wooden sickle instead of a wooden sword - at least that's what I do. More sickles is a small light weight mod that I'm sure you will use, if you don't it dosen't bother me. But why not give it a try?
