Thread starter
I thought this statement was interesting - and seems to make sense:
"Standard versions have the flare from the initial forging process, but the primary reason is to give the tip extra strength. The flared wings buttress the tip along its length. Cabinet screwdrivers are more likely to twist or break with too much torque applied, or when used to pry."
