At home or in the field?
In the field, take along pieces/sheets of 400 grit and 600 grit silicon carbide wet&dry automotive finishing sand paper. Wrapped around any mandrel and straight strokes.
At home, I use a 10X loupe under a LED light to inspect the edge. To decide which grit to start with. I'll go to 1500 with my wood carving tools then hone with CrOx/AlOx on some simple form of card stock strop taped to a flat surface or wrapped once again around mandrels.
For all of my carving adzes, I find that a tennis ball is a useful shape.
