What should you avoid doing when maintaining wooden handles on tools?

When maintaining wooden handles on tools, it is important to avoid coating them with paint. Applying paint to wooden handles can create a barrier that traps moisture underneath, which can lead to the wood rotting or deteriorating over time. Paint may also obscure the natural texture and grain of the wood, making it difficult to detect any imperfections like splinters or damage.

On the other hand, varnishing is often recommended as it provides a protective layer that can enhance the wood's durability while allowing it to breathe. Regular cleaning helps to remove dirt and oils that can accumulate and potentially degrade the wood. Checking for splinters is also crucial as it ensures that the handle remains safe and comfortable to use, preventing injury during operation. Thus, avoiding paint helps to preserve the integrity and safety of wooden tool handles.
