Nested knife-set

Nested knife-set:

The Deglon Meeting Knife, designed by Mia Schmallenbach, is a set of sculptural, nested knives (priced, alas, as sculptures, at $600 for the set). The proportions of the four nested knives -- paring knife, carving knife, chef’s knife and filleting knife -- are "determined by the Fibonacci sequence with as its base the average width of a hand."
