I have several Shun Pro knives, and they are probably my favorites out of my (ridiculously large) collection of kitchen cutlery. This particular knife is one of the most useful of all. However, knives of this design are probably not the best choice for the "average" cook.
First, recognize that this is a single-bevel knife of Japanese design. Moreover, the "flat" side is actually slightly concave. This design has advantages and disadvantages. First the advantages. It takes a very sharp edge, and the excellent, relatively hard steel holds this edge very well. The concave "back" allows the knife to pass through foods much more easily than a conventional knife.
Now the disadvantages. the single bevel causes the knife to "move" toward the flat side when you are making a cut. With a little practice, you can compensate for this and produce perfect, paper-thin slices -- but it does take a bit of practice. A second disadvantage is that you should not sharpen knives of this type with typical sharpeners. The beveled side should be sharpened to 17-20 degrees, and the flat side should be finished at near 0 degrees. Unless you are experienced and equipped properly, you should have this type of knife professionally sharpened. It should not be run through an electric sharpener -- even the Chef's Choice, which works OK for conventional knives.
The blade has fairly little "rocker." It is best used for slicing and chopping (as opposed to the type of rocking action you can use with a typical chef's knife).
This is an absolutely wonderful piece of cutlery if you are prepared to (1) learn the characteristics of a single-bevel knife; (2) sharpen it properly.
