This pattern welded spear head is based on a find from the Hereford Musuem collection. It is a Petersen type K spear head with a very intricate pattern welded blade. The blade is made up of four parts:
 
An inner wedge of plain steel
Two middle layers of pattern welded bars twisted clockwise and anticlockwise and
A cutting edge of straight laminate pattern welded steel
 
The socket is also decorated with bands of inlayed copper alloy.
 
This highly decorated spear head clearly belonged to a person of power and status.
