Eons ago when hf carried chisels that are now the same as the aldi chisels, I bought a set to grind and try various things. They became the "house chisels". Same type of thing, any time you want to hack away at something or chisel off old adhesive that's got grout or plaster or something on it, out come the house chisels.

Despite what sellers says, they're probably not as good as your sandviks.
