No Callouses From These Tools (May, 1932)
No Callouses From These Tools
TOOL handles with cup-like depressions in the sides are now available to workmen. It is claimed that the depressions form a vacuum when the hand presses against them, helping to maintain a firm grip on the tool without grasping the handle so firmly as to cause callouses.
So, instead of callouses, do you get suction marks?
Hammer hickies!
Sure don’t look pretty.
