A hand point is tapered at the end in all directions down to a very sharp point. This concentrates all of the hammer blow onto one spot. I have never met a rock that can resist a carbide-tipped hand point. Carbide tip hand point and hand chisel. The tip has an insert of very hard carbide material.
Carbide is very hard, but it is also brittle.
You must resist any temptation to use these chisels as a prying tool. The carbide will break off. Fortunately you can have the carbide tip replaced by the manufacturer. This is much less expensive than replacing the entire chisel. Whatever chisel you use, make sure you keep it sharp.
