The 7 1/2" Mallet features a dual-head design with one nylon head and one stainless steel (SS) head. The nylon head weighs 7 oz and is ideal for tasks that require a softer impact to avoid surface damage, making it suitable for woodworking, metalworking, and other precision tasks. This mallet offers versatility for different types of work, allowing you to switch between the two heads based on your specific needs.
