Cleavers do many things. Id do the very heavy work with a BB&B cleaver ( 20 % Off !) there kind you would find in the blister-packed section.
don't spend a lot there, just not too little. If you ever get to a real Chinatown, they have all steel cleavers there that are numbers. get one of theses, or a blister-pack
BB cleaver of the same size or the next one up. thats for the heavy work.
use this one for finer things : soft chicken-bone chop-ups, etc
look the Global over for nicks. use any magnifying glass you have or borrow one 10 x or 20 x is all you need in good light.
Globals are gems for balance , holding a very sharp edge if used carefully etc.
I don't know what Golbal itself recommends for the edge angle for the cleaver, but you might Google that up.
go to a decent knife store if you can find one in your area, or consider
if you want to have a great deal of fun go here :
that's where I learned so much about Global Steel.
best of luck.
of course, store it carefully as you would any fine knife os the edge does not get damaged in storage
