what do you call a considerable amount.
Really it is down to preference and the only way is to go to a kitchen shop and try them out. see how they fit in the hand. I find global handles to small and to slippery (I have hot hands). Equally I find henckles to heavy and handles are to big.

Global
Henckels
Wusthof
The knife I use time and time again is a ~6.5" chefs knife.
The knife is will be used by the Family. As for budget i would say £60 - 70 is a decent amount for a good quality knife?


f.dick or victorinox, geisser/messer are also top quality, i work in the trade and you will see chefs using globals but dig deeper and you'll find they are given/paid to support their brand, i used a sabatier once i found it harder to put and edge on and it didn't keep plus i ender up snapping the thing they are a very rigid blade.
Global etc are fine for kitchen use but put them in the hands of a pro and they will more than likely tell you to bugger off, the lack of a hand guard is also very disturbing.
The ones i suggested won't be as easily available but they are worth it, have a nose in your local butches or supermarket the coloured knives you see will be the ones i suggested.
I've worked in a boning hall for nearly 20 years btw just so you know.

An interesting thread. I have lived most of my life with a useless knife I picked up for a fiver from Asda. I am really thinking about getting some new knives but my question is:
If you get a largish cooks knife for multi-purpose, what sort of things would you not use it to cut? People often say to avoid cutting tomatos, why?
Edit: I have no knowledge of knives what-so-ever.
