I can recommend Global knives, they're certainly not cheap but they're wonderful!
I started collecting them about 20 years ago, I'd save up and buy one every couple of months.
I like them so much that when we go on self catering hols in this country, they get put in a knife roll and taken with me!
Having really sharp knives makes such a difference to food preparation. When DS was away at Uni he had Ikea knives, which were okay for a student, but as soon as he could afford to and had a place of his own, he also started collecting Global, and they featured highly on the wedding present list!
I keep mine on wall mounted knife magnets, so that they don't touch against each other, which blunts all knives.
Whatever type of sharp knife you use, never use a glass chopping board, they ruin knives faster than almost anything else!
