Sheila Dillon takes a look at that most coveted of kitchen tools; the knife.

One of the most primal yet treasured implements, any chef worth their salt knows that you don't mess with another chef's knife. Sheila talks to chef Henry Harris from Racine's restaurant about his passion for knives. There's a report from a knife shop where the prices reach into the the thousands. With knife skills courses popping up all over the country, this programme is a celebration of the craftsmanship and artistry of knife making and of the people with a passion for this ancient tradition; from the home cook, the new chef buying his first set of knives, to the people who hanker after the rare Japanese blade.
