Wrenches can make excellent handles for heavy buckets
This hack is not a typical hack; it comes from an old book published during the Soviet era. This Soviet hack was used to improve the efficiency of water transportation at the time. Everyone knows that when buckets are full of water, they can be extremely heavy.
The handle can either bend and break or can hurt your hand. This illustration shows that a wrench is a perfect tool to prevent such accidents or injuries from happening. It just goes to show that solutions can be found anywhere, even inside outdated Soviet books.
