Blade guards are protective devices designed to cover the blades of tools and machinery, such as table saws and band saws. They help prevent accidental contact with the sharp edges, reducing the risk of injuries during operation or maintenance. Blade guards can be fixed or adjustable, allowing users to see the cutting area while still providing safety. In addition to safety, blade guards can also help keep the blades clean and free from debris. Many guards are made from durable materials like plastic or metal, ensuring they can withstand the rigors of a workshop environment. Proper use of blade guards is essential for safe tool operation.
