Even though it's a bit pricey I like this sharpening system because it is lightweight, sturdy, compact, lubricates with water and the diamond stones cut quickly plus it's a real sharpening system not a plastic toy.  At home I prefer to use oil stones and finish with black Arkansas.  I used to be a fine furniture maker and would get my blades literally razor sharp.  But that's all pretty much macho stuff since after the first pass the blade ultimately loses its super sharp status and becomes merely sharp, or dare I say, sharp enough.
