To maintain your hammer's longevity, periodically apply boiled linseed oil to both the handle and the hammerhead. It's natural for wooden handles to break sometimes. However, by oiling and being cautious with the hammer-handle connection, such as avoiding dropping it on its handle, you can prolong its life. Refrain from hitting hard surfaces with the hammer, as metal-on-metal contact can lead to dents and potentially hazardous chipping. If the hammer's face shows signs of wear over time, you can refresh its appearance using a Trizact belt and a buffer. This will keep it looking neat and polished.
