The coticule is an 8000 grit stone which puts it firmly in the camp of "finishing stones". To set or reset a bevel you need a much coarser stone or you'll be honing forever. I reset bevels on a Shapton 1k or a DMT8E (1200 grit). It should take only a couple of minutes. Once you've got the bevel right from heel to toe on both sides, then progress upwards through the belgian blue 4k and then the coticule 8k. Use the right tool for the right job.
