DIY metal file cork handle, Digi Mart USA News: Many metal files are sold without the handle that usually comes with them, leaving the tang exposed. The publisher notes that using a file without a handle is not recommended, because the metal end can cause discomfort and, if too much pressure is applied to the base of the palm, may injure the hand.
A common solution is to buy a universal handle, such as an internally threaded screw-on handle or a wooden handle. For those who want to avoid a trip to the hardware store, the publisher suggests a wine cork can provide enough cushioning in a pinch, repurposing an item that would otherwise be thrown away.
According to the article, champagne corks with a wider design and rounded top are more comfortable and rest well in the palm. Their bulk may also make them easier to grip for people with smaller hands than longer, slimmer handles.
Sparkling juice bottles with corks are another option for non-drinkers.
To fit the cork, the article recommends drilling a pilot hole into its flat surface, with the depth matched to how much of the tang will be covered. A hole that is too shallow may let the cork fall off, while one that is too deep may cause it to split. Once drilled, the tang is worked gently into the hole until it feels secure. Some people force the cork on with a hammer instead, but the publisher says drilling makes the job simpler, protects the cork and keeps the handle straight. Without a drill, more manual force and caution are needed.
