An interesting aside regarding blunt tips:

Table knives all used to be pointed. Now they have blunt tips. From the Wikipedia article on table knives:

The distinguishing feature of a table knife is a blunt or rounded end. The origin of this, and thus of the table knife itself, is attributed by tradition to Cardinal Richelieu around 1637, reputedly to cure dinner guests of the unsavoury habit of picking their teeth with their knife-points.[1]

Later, in 1669, King Louis XIV of France banned pointed knives in the street and at his table, insisting on blunt tips, in order to reduce violence.[2][3]
