What charliemuingus said – chinese supermarket and get something like
£4.50
small cleaver
I use it for everything but chopping through bone (different cleaver for that) – even peal fruit with it.
Also get youself a diamond stone stone. Super easy to use. If you sharpen your cleaver every week you will need a new cleaver in about 5 years.
I also own a few of the German soliegen knives above and some pressed knives but the cleaver is the most used by far.
