First round was onion: cut in half widthwise, peel, take five full round intact slices in one minute, then dice the remainder in 45 seconds. Smallest consistent dice was one goal; slice judging criteria was unclear. They ran out of onions and substituted tomatoes for some contestants.
Second round was julienning a ~4" section of zucchini in two minutes, aiming for smallest julienne.
Third round was cutting chives in 45(?) seconds, aiming for thinnest full sections.
Not all competitors got to make each cut - some were eliminated in each round, rather than using cumulative scores.
There were tomatoes and lemons present, but neither were used except as onion substitutes.
Work surfaces were poly boards on folding tables. Several competitors appeared to have difficulty with the slipperiness of the boards.
Murray used his "perfect kitchen knife" rather than a Spyderco. He gave it away after winning.
