Sharp, The sharpmaker works with large knifes once you get the hang of it. The key is to do it in sections, the first 4" then the middle ect. Finish with a strop and the edge will be uniform. However, The weight of and sharp or large blades do make it much more awkward. If you mainly plan on sharpening knifes larger then about 5 inches I wouldn’t recommend it. It really shines on smaller blades.
Joe, like many things it’s all about practice. It’s taken me years to be able get a blade this sharp, but if you devote the time, you can too! The key to remember is be patient and be gentle. What setup are you using now to sharpen?
Lighthiker, I cant give you how long for sure, as I work on the knife during commercials, but I'd guess reprofiling was 2 hours, and sharpening and stropping was about 20 minutes. You have to remember the knife only has to be reprofiled once. What equipment are you using?
If anyone is interested there are good sharpening videos here:
