ok maybe you could narrow it down from a 'nice knife' if you dont suggest a mora?
Well my favourite knives are my Randalls, but they are pricey, on the other hand I believe they will never break and always bring a smile to my face when I go to use them, but they are at least a dozen custom knife makers here who could either sell you one of their in stock knives or make you something custom.
If you are looking at factory knives then ESEE make good ones with an amazing warranty, Svord knives are good cheap and cheerful, Gary Mills makes very good knives and is a pleasure to deal with, Mark .177 builds nice looking blades and hillbill (I think thats the name) makes nice ones too, Ben Orford, lots of makers, just depends on what you want and how much you want to spend.
