n 1669 King Louis XIV of France decreed all pointed knives on the street or used at the dinner table 'illegal' and he ordered all knife points ground down, like those similarly used today…in order to reduce violence!
Other design changes took place following the grinding down of the knife point…cutlers began to make the blunt ends wider and rounder to make for ease of use, in combination with the early 'two pronged' fork. Many knives were designed with handles rather like 'pistol' grips and a blade which curved backwards so that the wrist would not have to be contorted to get food to the mouth!
