This goes along with my recent thoughts of a streamlined kit.
1. Heiji 210mm semi stainless gyuto.
Perfect for line use. I had this made with a Heiji interpretation of a Sabatier profile and it fits right into the expo station at work.
2. Heiji 240mm carbon gyuto.
I just got this knife and really like it. Good for large prep projects, not as good for that as my Watanabe was, but much better for portioning proteins and slicing large things.
3. Shigefusa 300mm yanagiba.
I spent a year and some butchering, portioning, and slicing fish for 6 or 7 of my ten to twelve hour days I got to really appreciate what a yanagiba has to offer vs a gyuto for these tasks. This is one of the better ones I've owned, I would happily use a similar sized Masamoto KS or white steel Watanabe.
4. Watanabe 210mm deba.
What I said about the yanagiba, but sub deba. I'd be happy with the Watanabe, a KS, or a Shig. Any well made, easy to sharpen deba. If my bag disappeared (knocking on wood) I would probably replace the single bevels with Gesshin Uraku, at least in the short term.
5. R. Murphy carbon boner.
The best boning knife I've ever used. I'm not a honesuki guy, this is what I use for poultry as well as pastured critters.
This is pretty much the only knives I pull out of my kit now. I just got an Uraku 270mm mioroshi deba that might be able to replace the yanagiba and deba, and bring it down to four. Maybe I would upgrade the Uraku to something fancier, but maybe not, they are pretty damn nice.
If I ever start cutting up land critters again I would add a stiff breaking knife. I used a Bloodroot that I really liked, but I have never shopped for a high end breaking knife.
