My wife is a serious home cook, teaches cooking classes, etc. & her favorite by far is a Japanese Global G-2 chef's knife, approx. 8". This and a cheap little Victorinox paring knife are about all she ever uses. We also have a Victorinox chef's knife that I tend to use because the large wood handle fits my hand better than the Global.
If you are on a budget you really can't go wrong with Victorinox; I think our chef's knife cost about $30. We also have one of their serrated bread knives; got it for a wedding present 25 years ago & it is still going strong. I touch up the serrations from time to time with an EZ Lap diamond steel.
Hope this helps; bon appetit!
