Good you like them!
Butchs knives are the quintessential: Here I come, get out of my way, Im serious about this protein/vegetable kind of knife... They are a lean-mean slicing machines... They just do their job every time...
Ive had a really good experience with his CPM154 knives. Little maintenance good retention and good edge attainment.
His profiles are spot on, I wouldn't change a thing. Ummm... Really. Cant think of an aspect of his profile that needs tweaking. I specially like those corners and the curve on the nakiri. Its right where it has to be (you know what I mean). They are on the beefier side of the spectrum.
And his handles are very well executed to boot (for larger hands though). I like them so much, I am thinking of getting one of his gyutos or/and petty one of these days. :viking:
