This was from a knife handling class at Williams Sonoma in the Time Warner Center, here in NYC. While both of these techniques work very efficiently, the first one is more suited to "restaurant" slicing, ie, the emphasis is on cutting identically sized pieces for maximum visual effect but more waste, while the second is the "kitchen" technique which uses more of the vegetable with mix of sizes and shapes of pieces. Note all scraps go to the "vegetarian dog."
This is at the Borders bookstore at the Time Warner complex on Columbus Circle, NYC. I took these photos to show how David's new book is being is being placed on the shelves since his book is all about tagging and classification.
