Good thinking.
Here's a link to the IB-8 stone I told you about:
Norton 8 x 2-in. India Combination Oil Stone - Norton Sharpening Stones
Learning to use stones isn't that difficult. Don't be intimidated. Learning to use one really well, takes some time though. I learned to sharpen in the Cub Scouts, more than forty-five years ago, and I'm still learning. You can practice on your Wal-Marts. If and when you buy a stone, let me know what kind and I'll teach you how to use and care for it. Remember that the IB-8, by itself is a stop gap. At most, it's only part of a set of stones. You'll either add to it or switch to waterstones with your first really good knives.
As part of your knife care regimen you'll also
need to purchase a suitable steel if you don't already have one, learn to use it, and use it frequently. I'm sorry for not mentioning this before. If you already own and use a steel, you're more than halfway to knowing how to use stones.
The Hiromoto and the Calphalon are both
san mai. Let me explain. A san mai knife is made of three layers: A thin, hard steel core sandwiched between layers of softer steel. The outer layers are called
jigane, and the core is
hagane. The idea is that the flexible outer layers protect the hard steel from chipping, dinging and breaking. Their softness makes a
san mai blade easier to sharpen than a blade made from a
hagane only, because most of the metal you remove is soft.
Warikomi is a type of construction, and a term you might run across. It's very similar to
san mai. Although they're slightly different, for practical purposes you can regard them as the same.
The Hiromoto
hagane is made from a kind of steel called "
Aogami Super."
Aogami is a trade name for a group of of steels made by the Hitachi foundry. "Super" is a particular flavor of
aogami. The word
aogami means "blue wrapper," because the steel is shipped in blue paper.
Aogami Super is not stainless, but it's actually fairly stain resistant as carbon steels go. It takes an edge extremely well, holds it unbelievably well, and considering how hard it is, is extremely resistant to chipping. Hard to sharpen, though.
The Calphalon
hagane is made from a steel called VG-1. The VG family is a group of stainless steels that were initially developed especially for knives. As stainless goes, VG-1 is very good. It sharpens more easily than similarly hard non-VG steels, and is more flexible and ding resistant. In the case of "damascus" look (look because they aren't really damascus), the
jigane is composed of layers of very soft stainless -- usually 403. (I'm not sure, but believe the Calphalon
jigane is 403.) The
jigane is ground than acid-etched to bring out the pattern. The layering and patterning does nothing for performance, but is quite attractive. The Japanese do not call it "damascus," but "ink pattern" because it looks like water that has had a drop of ink put into it. For a VG-ink pattern knife the Calphalon is very reasonably priced. The Calphalon is made to look a lot like a Shun Elite or Classic, and out of similar materials. But the grinding is different; the Calphalon is not as thin and won't give the same high level of performance. Also, the handle is highly stylized and idiosyncratic; you won't necessarily like it.
Please tell me what you like about santokus specifically, and why you're choosing one instead of a chef's knife. As I said, their appeal is a mystery to me, and I'm very interested in learning why others prefer them.
