I'm not a fan of double bevels and the only place I use them are with my two Zowada's. They came with double bevels and the first time I needed to hone them I removed the Double bevel in favor of a single however I found the edge simply did not hold up with a single bevel. After about 10 shaves the blade would increasingly microchip just from use. I went back to the double and the edge holds up much better.
