Thanks for the feedback. The 600 chosera was also used and is the blue hone pictured. I'm not a big fan of slurry but have used it in the past. I was able to get the edges to the point a slurry would bring them to but the edge would not go past that point. Once I switched to the Norton there wasn't any problem. As I noted in other posts, the hardness of the blade and the binders/grit material in the hones can effect the speed at which a bevel is set. This combination in the Nortons worked best for these particular razors. I'm sure I could have gotten the chosera to work but having other hones available brought me to the finish quicker than experimentation would have with my limited free time and my time line. The right tool for the job at hand matched with skill set is always best if the tool is readily available and on hand. :)
