I need a chisel primer! I have a set of chisels I inherited from my dad, they have beveled edges and plastic handles--probably about 40 years old. The end of the handles are flat and obviously made for wacking with a hammer. I have another set, also with beveled edges, but they have longer, thinner handles, which are kinda pointy on the end so I don't think they are made for pounding. I've heard of bench chisels, paring chisels and mortise chisels--How many categories of chisels are there and how do you tell them apart?
