For vegetables I haven't come across anything better than my 7" scalloped santuko. We cook A LOT here in my house and I have a full set of knives and the santuko gets used probably 4x as much as all the other knives put together. Next up would be a 4" paring knife and our 8" serrated (bread) knife. The others really just sit in the block unless their buddies are dirty and I'm too lazy to wash one of them!
I haven't looked at ad hoc at home but I would say that a 10" chef's knife is too big for most people unless he's saying 10" AOL - kitchen knives are usually listed as the blade length, not the OAL, and a 10" blade is massive for a kitchen knife (unless its a salmon fillet knife or a slicer)...
The santuko is equally fantastic for meat but chopping veggies is where she'll shine. If I had to replace all my knives I would buy another 7" santuko, a 5" santuko, a bread knife, a 4" paring knife and possibly a fillet knife (but only because we eat a lot of fish). Scalloped edges on the santuko really helps reduce drag and friction as you're cutting and makes cutting veggies a lot easier, IMO, some people hate them but I love them. I haven't used one personally but a lot of people really love 3-4" straight (wharncliffe) blade for veggies/fruit, especially if they do a lot of canning. For blade shape I would look at major brands that cater to chefs and see what styles they have in their chef lines of knives - they are making them for people who will use them for hours on end every day. I really like Henckels knives but check out Wusthoff, Shun (a little different) and others and see what you think your Mother would like. I would love to walk into my parent's kitchen and throw away all the crap knives they have and replace them with a hand-crested set that I made personally for them... Someday maybe!
Since I don't have the money to spend on the knives (kitchen or otherwise) that I want, we bought Henckels Twin S forged knives with money from our wedding and we have been very satisfied with their performance and, like I said, we cook a lot (I'm in Chiropractic school right now but had a hard time deciding between Chiropractic and Culinary Arts).
When I first saw that you were going to use G11 I was a little worried but with your bead blasted finish I think they will be awesome. Most kitchen knives I've seen with G11 are finished to a beautiful glossy finish that is slicker than snot in the kitchen which is so incredibly dangerous. I think A2 will be a wonderful steel and will just get better with age.
BTW - how did you go from WA to Provo of all places??? I grew up in OR and my fam now lives in UT (many in Provo) but I would pick WA over UT any day of the week!
