Given the amount of travelling I do, and the odd private chef gigs I take on, I often find myself cooking in other people's kitchens. I love exploring other people's kitchen, but one of my biggest pet peeves is a kitchen with a large collection of cheap dull knives.
You really only need a few really good knives, and once you invest in good knives, it's crucial to keep them sharp. Sharp knives not only make it easier to make your food look great, they prevent injuries because you don't have to use a lot of pressure to slice something.
The Chef Knife Guru over at Cooking.com has put this awesome infographic together which sums up pretty much everything you need to know about kitchen knives. If you know someone who needs help in the knife department? Do them a favor before they injure themselves and share this with them!
