I'm looking into a knife sharpner. The sharpmaker was recommended. What is the difference (if at all) between the 203 and 204. At some point in the not too distant future I'll have a need to sharpen a number of my knives (Spyderco Goddard c18ps (partially serriated), my Busse infi steel BM, and a Dozier D2). Is the sharpmaker the right tool for the task?
