Morphology
The noun phrase is directly compositional: 'abrading' (removing material by scraping) + 'stone' yields a stone used for abrading, so a learner who knows both constituents can infer it denotes a tool for grinding/smoothing. The gerundive modifier + noun pattern meaning 'tool used for X' is common cross-linguistically, reinforcing predictability for a B1 learner.
Etymology
Abrading stone is the name for a simple tool made from a rock that people rub on other things. The word abrading means rubbing away and stone is the rock, so picturing someone rubbing a rock on wood or bone helps you remember it was used 'to grind', 'to smooth', or 'to sharpen'.
