Go for the balsa or a scrap of leather froma shoe repair shop for the pastes. Do not apply them to your good Dovo hanging strop.

The Edwin Jaegger is likely a made to order Dovo product. You may well be able to sharpen this to shave ready on the green and red pastes with some work. I have done many new Dovos using only pastes from 9 micron to 0.5 micron.

Keep us posted on your progress.
