You might also check out Thiers-Issard's diamond razor sharpening paste in crayon form at Classic Shaving & several other online suppliers. It's made by a name brand razor company. I'm thinking about trying it but have not yet used it. I've been using a 12K Naniwa or Coticule finishing hones followed by stropping on 0.50 micron Chromium Oxide sprayed on balsa wood. Straight razor shaving is a hobby whose enjoyment comes from not only the mastery of the skills of shaving or from close comfortable shaves but also from the pleasure of discovering new untried products and methods from the huge variety of options available that enhances the pleasureable pursuit of this hobby. Good luck in your pursuit-Have fun
