Using the GT jab saw is a breeze. Just hold it by the ergonomic elastomer handle and use it to cut through drywall. When the blade gets dull, simply replace it with a new one. Remember to wear safety gloves to protect your hands while using the saw. To keep your saw in good condition, store it in a dry place. If the blade gets dirty, you can clean it with a dry cloth. Avoid using the saw on materials it's not designed for, as this may damage the blade.
