Look up norton jb74 machine knife stone. The groove is to protect your fingers.

I've seen axe stones with that groove, too.

how does it work?

Hold the axe in one hand, and cup the stone in your palm, with fingers in the grooves, keeping them well away from the exposed face of the stone.  Lubricate the stone (spit was common when doing sharpening in the field) and rub it over the edge.  As with any sharpening, you're abrading to a sharp edge.  Most axes, except side axes and the like, have two bevels meeting at an edge, so you'd work both faces.

This 4" round silicon carbide (Crystolon) stone has both a coarse side (120 grit) and a fine side (320 grit). Used for sharpening and honing paper and cloth-cutting knives and planer knives. The groove around the middle of the stone protects fingers and provides a secure hold. 4" in diameter by 1.5" thick.
