knife quality

I am new to this I have the following question.

I am quite happy with cutco knives, what do I look for to get the same 
quality from another manufacturer.  Cutco knives stay sharp for a long
time. 
Even when they are dull, they are much sharper than anything else in my 
kitchen.  I think cutco's prices are high, so I want something similar or 
the same for a lower price.
