Abstract
A tear strip is formed in a paperboard container blank by scoring a line of weakness on each of the opposite surfaces. The lines are offset from each other to form between them an area where the piles are easily separated. One or both lines are formed by impressing the blank with a diamond pattern knurling tool.
