Using these tweezers is easy. When soldering SMD/SMT components, just open the tips and gently pick up the component you need. You can hold it firmly in place during the soldering process or hot air rework. Remember, these tweezers are fairly pointy, so be careful not to poke yourself or damage other parts. As for maintenance, keep them clean after each use. You can use a soft cloth to wipe off any solder residue or dust. Store them in a dry place to prevent rust on the metal body. And if you want a different level of sharpness, there's another version available for you to explore.
