You have good questions. All of them make sense too, once some of the assumptions are teased out and examined.
Shun Classic
You already bought a bunch, but you ask whether you should keep them or eat the $20 restock and re-ship fees.
Hmmm. You already described your ideal knives as something very much like Shun. Is that your ideal, or your wive's?
I can't recommend the Shun Classic chef's knife at all, because the geometry is so incredibly bad. The worst two aspects are: (1) It's tip is way too high to get down on the board, as when cutting onions; and (2) It's got way too much belly -- more German than the Germans.
To the extent that people tend to be Shun lovers or haters, I'm a hater of the chef's knife, but a skeptic of the rest.
The other great weakness of Shun Classic, and true across the line, is the indifferent quality of their faux Damascus (aka suminagash) cladding. It looks pretty -- but not for long -- it just scratches and fades way too easily. Impossible to maintain, no matter how careful you are.
Otherwise, their fit and finish is excellent. Almost everyone finds their "D" handles comfortable -- as long as they're properly handed. That is, the handles are either right or left handed, and do not work well for an opposite handed user.
Their VG-10 core steel gets pretty sharp and fairly easily too, if you know hot to do it. It holds the edge reasonably well. The edge can be fairly easily maintained between sharpening with appropriate "steeling."
Santoku vs Chef's Knife:
Given your budget and aspirations -- choose one or the other. If this is really a gift for your wife and she wants a santoku, ixnay the chef's and spend the money elsewhere. There's nothing a chef's knife can do that a santoku won't. In my opinion a chef's knife is a better knife than a santoku, but we care about she and not me.
How do you spell redundant? Oh. Wait.
Tojiro DP
They used to be a lot of knife for the price. Now, since the price increases of the last 14 months or so, they're just one more knife at a crowded price point. There are plenty just as good or better: Akifusa, Fujiwara, Hiromoto, JCK Kakayagi, Kanemasa, Kanetsuga, MAC, Masamoto, Misono, Sakai Takayuki, Thiers-Issard "Nogent" Sabatier, Togiharu, to name the first dozen off the top of my head.
Also, the DPs are not what you'd call real good lookers. Quite the reverse.
Black Kanji:
If it's screened on, it will die quickly. If it's engraved, different and happier story. If you really like the kanji, don't go for black -- like Hattori or Shun; go for engraved like Hiromoto and Masamoto.
Which Profiles Should You Buy?
- Santoku: Again, chef's or santoku. If they're her knives, don't waste your money on both. You can buy a chef's knife later. If the chef's knife is for the other cook -- that's a different story. It's the knife which will be used most often by far, it's where the money should go.
- Petty: The switch from a small paring knife to a 5" - 6" couteau office as the linch-pin short knife in a pro set, is fairly recent and appears to have begun with professional chefs cooking Western style food in Japan. I like it. If your wife likes it too, get a good one; but don't bust the budget on it. At this length, the Shun is actually a fabulous knife as long as you don't give a rat's patoot about the pattern holding up. While it wouldn't be my choice -- there are dozens I'd prefer to Shun -- it's still a good one.
- Paring: Go cheap young man. If you need special shapes like bec d'oiseau for turning, or your wife can't live without a sheep's foot -- or she wants a short couteau office -- look at Forschner Rosewood, Forschner Fibrox, F. Dick, etc. And by the way either count on sharpening this little knife yourself (they dull fast because of all the fibrous work they see) frequently.... Or, consider buying a half dozen disposable Forschner serrtated paring knives (about $5 each), Kiwis, or something equally cheap, and tossing them when they get dull.
- Bread: There's one standout in the under $100 class, and that's the 10.5" MAC Superior. If cutting bread and cakes isn't a big thing in your house, forget the MAC, as good as it is, and save some money with an 8" generic. Forschner Rosewood are very nice.
- You didn't mention it, but it's one of the four knives every pro set should have (Chef's, Petty, Bread and Slicer). If you have the time to reach for the "right" knife, the better a cook you are, the more you tend to use a slicer for portioning. It's really an important knife. My recommendation is to buy a top quality slicer.
- Honesuke (rant!): You absolutely, completely, unequivocally do not need a honesuke. It adds nothing whatsoever to what a petty brings to cutting up a chicken. If you're not doing Japanese style poultry butchering, and you're not a knife hobbyist buying a knife for something other than what it actually does -- it's a waste of money.
Chances are huge you don't need any sort of "boning" knife. But if you do, get a Forschner Fibrox or Rosewood, or a Dexter Pro in whatever profile(s) are most useful for the types of butchering you actually do.
I learned to cook in the sort of brigade system that had me at the "boucher" station for about six months; and now (decades later) have five specialty profiles -- desosseur (aka "European" boning knife), wide fillet, cimiter, chef de chef (aka "lobster cracker"), and heavy cleaver -- which do suit my style of cooking exactly, and seldom use any except for the chef de chef. I still do some boning, but find that my "petty" (a Nogent 6" slicer) works almost as well as my desosseur for fancy "boning-out," and it's a lot easier to keep sharp (big issue with boning knives); and it has a better handle too!
And, a similar truth with fish. I now fillet smaller fish "Japanese" style, except I use a little 7" chef's the way a Japanese cook would use a small deba. If I didn't have that knife, I'd happily use my 10" chef's or the 12" chef de chef to cut through bones, and break the fillets out; and my slicer for everything else.
Fujiwara:
High performance compared to... oh... say... Henckles International; but just adequate by Japanese knife standards. Because of their low prices, you'd have to call them high value. Mediocre fit and finish (at best).
Togiharu:
You say you're close to Korin. Go there and look at the Togiharus. The G-1s might be out of your price range, but you can afford the other lines. Togiharu is Korin's "private" brand and there's a lot of value in them.
Hiromoto G3:
These are beautifully designed and quite reasonably priced. Hiromoto's big claim to fame is providing really excellent steel at a good price. Some cooks find their handles to be too narrow; but I've never heard the complaint from a woman -- even ond using a "tennis" grip. After reading your post, this would be my top recommendation for both santoku and slicer. Heck, throw in the petty just to make Koki (at JCK) happy.
Other brands:
I don't want to go through a rundown of every Japanese knife known to man. For one thing, I just posted one on CT a couple of times.
Cutting Board:
Just go to a good restaurant supply and get a maple "edge grain" aka "long grain" cutting board -- at least 1" thick. If you need a name brand, get a Boos; but it doesn't matter that much. Assuming it was adequately made to begin with, treat it right and it won't crack or warp for a long time. Next year or the year after, you can invest in a Boardsmith. Nice to be able to rotate boards -- they last about four times as long if you do.
Sharpening at Korin:
Some people get the idea that good knives only need to be sharpened once a year -- and can be maintained between sharpening with a "V" stick sharpener and/or a rod-hone type "steel." Not true.
If you're active cooks, and you want knives with edges which don't wear to "very dull," you'll need to full-on sharpen your chef's and petty at least every three or four months. That's independent of "touch ups" with a steel or "V" stick, by the way. Those you'll use a couple of times a week.
I sharpen my main knives every 6 to 8 weeks at the longest; and maintain them on a steel at minimum 3 or 4 times a week.
What I'm getting at, is that if you can afford to have your knives sharpened by Korin, Japanese Knife Sharpening, or whomever, that frequently -- that's great. But, you'll still need to use some sort of appropriate regimen (which in particular depends on the particular knives -- but probably steeling) to maintain them between those expensive sharpenings.
No hurry on this, go with plan A for awhile. But when you get tired of sending your knives out every 12 weeks, or alternatively, spending most of the year with dull knives -- you might want to consider some form of sharpening less intimidating than freehanding on stones. There are a few.
