HI!
I have had three or four Bohlers, a couple of JCs and three Bismarcks. The Bohlers take a very good edge, but are prone to micro-chipping and over-honing, so a very light touch is necessary. Don't be surprised if a small burr forms and you have to drop down to a coarser hone to get rid of it (back-honing to remove the burr them some light normal honing before moving back up again). They don't all micro-chip but when they do it is very frustrating. Stones that form a good slurry help, and specialist stones like the Tam O'Shanter are good at preventing this from happening.
The JCs have been a bit of a mixed bag - when they are good they are very, very good but when they are bad they are horrid! Main problems with them are warps leading to uneven bevels. Severe cases might be impossible to hone to shave-ready. Check for warps by looking along the blade and spine, and by opening the razor and laying the blade on a flat surface - if any part bows of doesn't tough its going to ba a problem - a problem best avoided!
Bismarcks - never had a problem with them. If you want to try honing, then perhaps you could start with one of these.
Regards,
Neil
