We've built up a set of Henckel Professional S knives over the past 20-odd years. They're still doing the job. Most of them, to be fair, are B-grade that we bought in TK Maxx. None of those B-grade knives have anything visible wrong with them. So keep an eye on TK Maxx for such things.
We also have a lone Global knife that's definitely a class down (even if it looks cool), though it's still useful on occasion.
I fancy a posh Japanese folded steel knife one day, but every time the KAS raises its ugly head, I baulk at the cost of one of the 'proper' ones, and put that KAS back in its box....
