The main body is similar to the stone masons chisels, which usually come with two options at the striking end. One is mushroomed over, for use with a wooden mallet. The other - which this looks to be like- is tapered for striking with a soft iron mallet. Though I note that there does not appear to be any telltale evidence of wear, from it being struck repeatedly.
The tips at the business end, of something like a replaceable-tip, scutch, have a ridge along them that stops the tips being jammed into the cleft of the chisel body, which would make them difficult to extract. This also allows for the tips to be double ended which the tip of the tool in question does not seem to be.
These observations would lead me to doubt that it was used for working stone.
