Hi familyguy!! Welcome to the board.
Knives are really expensive and in my opinion it is better to have one $100.00 knife than a whole set for $99.99.
I would look for Wusthof - 8" chef's knife - it's around $90.00 or one of my all-time favorite knives is the one sold on the Food TV Network -
WUSTHOF 7 IN. SANTOKU KNIFE HOLLOW EDGE
- It is a great knife!!!
Make sure she has a steel to sharpen her knives each and every time she uses them - really, really, helps.
Wow - I've been doing a little search and I think I have a winner here -
Wusthof Classic Cook's Set (4 Pieces) $149.95
Scroll down the page, I think it's the 4th set down - that's a winner in my book!!!!!
The 7" Santoku is a great option if you want to keep it even cheaper though - just be sure she has a steel. I use this knife for LOTS AND LOTS of things. It gets used every day - but the link above to the the set of Wusthof is a nice dream set.
