Most important tool in the kitchen? Your knife.
Every kitchen should have at least one good knife.
Mine has just that. One good knife.
If you are looking to buy yourself or someone else a knife, start with a chefs knife. Look for a sharp blade, good heft for it's size, and that it feels comfortable in your hand.
Remember you get what you pay for. If you spend $10 on a knife, chances are it's going to be crap. Spend $70 or ever more, you've got a better chance of it being a keeper.
