I have been cooking for 36 years and taught for 10 years at Le Cordon Bleu and have been teaching at Joliet Junior College for the past 13 years. I have been using the Classic Visual Knife Cut Models for over 15 years. I find this tool a great asset for students as it gives them a 3D visual aid to compare their knife cuts. I always find it difficult to give them a piece of paper to compare. But being able to actual see and match up their knife cuts to a “real” representation of a knife cut it awesome.
