My grail knife is probably a honyaki ashi gyuto.
I use my knives both at work and at home. I value functionality over asthetics but still value looks.
The bare minimun I would want is a 240mm beater gyuto, thin behind the edge 240mm gyuto, and 150mm stainless petty. Smaller pairing, chinese cleaver, honesuki, deba, slicer I like having. Gyuto, slicer, petty and single bevels can be more delicate but Id want everything else to be more robust. I generally like thinner knives. Dont have enough experience with single bevels to pick a grail.
I have tojiro 240 gyuto, gengetsu 240 semi gyuto, gesshin ginga 150mm stainless petty, mac pairing, rinkaku lefty honesuki, gesshin uraku lefty deba, cck chinese cleaver.
I'm perfectly fine with the knives I already have and almost all my bases are covered. Even with unlimited money I dont see a need to replace any knife I already have. I would still add a yanagiba, usuba, more gyutos and upgrade everything else for the hell of it.
