sharpening - today's tipette

After I've hammered in the pegs on the sides of the boxes they are faceted - I think there was a photo of this a lttle while ago.
A sharp chisel for this is essential so I thought I'd show you how I sharpen.
Two stones, one medium and one very fine - almost slate like, an eclipse jig and a couple of pieces of MDF glued up to make a measuring jig.
One side of the jig is for plane irons and the othe for chisels.
