What is the difference between a nail puller and a crowbar?

A nail puller and a pry bar are both popular tools in the DIY industry, but they have different functions and areas of use.

Nail puller: A nail puller is specifically designed to remove nails from wood or other materials without damaging them. It usually has a long, thin, and hard metal bar with two grip ends. One side of the bar has a pointed, bent end that can be slid under the nail head to pull the nail out. The other side may have a flat V-shaped slot for removing nails that are closer to the edge of the material. The nail puller is ideal for fine work or when gentle leverage is required.

Pry bar: A pry bar, on the other hand, is a more versatile and heavy-duty tool. It is usually larger and heavier than a nail puller and is designed to exert significant leverage. It can be used for breaking open materials, moving heavy objects, and removing nails. Many pry bars have a flat levering end and a bent end for removing nails, but their main function is prying apart and moving materials.
