It's entirely personal. There are members who've stated that a £5 knife from Tesco is enough. For them, it may indeed be the case. I started with victorianox, and have tried many different brands at many price points, be It global or otherwise. I'm a chef though, and as such it becomes about so much more than being sharp, I have to find something which doesn't feel like a chore to use in terms of how often it needs a proper sharpen vs putting it on a steel, or comfort, grip, blade profile etc. Robert Welsh were pretty damn close, amazing knives for the money, but i took the plunge and bought a kai shun and havnt looked back. If I was just cooking at home though, and dicing one onion instead of 40, then a victorianox would almost certainly have sufficed.
