Blumenthal performs TV car stunt with Grunwerg knife

Celebrity chef and culinary alchemist Heston Blumenthal has stunned a Silverstone race track audience with a daring car stunt involving a cucumber and a Tojiro Senkou kitchen knife.

The dramatic feat sees Blumenthal power sliding a BMW M5 around a corner of the track whilst trying to slice a cucumber using his favourite Tojiro Senkou knife, supplied by Grunwerg, attached to the front of the car.

Everything was recorded for Channel Five – so watch Fifth Gear on Jan 21 at 8pm to find out what happened!
