Digging through grandpa’s tools and found these weird pliers. They have a small brass dial with numbers on the nose and don’t seem to grip anything tight. Any ideas?

5. Decoding The Numbers On The Dial: Tooth Size And Set Angle
The numbers on the brass dial of a saw set reflect the tooth size and the corresponding set angle needed for different types of saw blades. Typically, smaller numbers correspond to finer teeth, which are used for more delicate cuts, while larger numbers are for coarser teeth, suitable for rough cuts.
Adjusting the dial changes the angle at which the tool bends each tooth, ensuring that the saw blade cuts effectively for its specific use case. Understanding and utilizing these settings can greatly enhance the performance of a hand saw, making this tool invaluable for woodworkers of the past.
6. Why The Jaws Don’t Grip Tight Like Normal Pliers
Unlike standard pliers, a saw set’s jaws are not designed to grip objects tightly. Instead, they are crafted to exert just enough pressure to bend the saw teeth without damaging them. The jaws often include a small anvil that supports the tooth while it is being bent.
This lack of a tight grip is intentional, as the tool’s purpose is not to hold objects but to delicately adjust the angle of each tooth. The design ensures that the force applied is controlled and accurate, preventing any unnecessary stress on the saw blade.
7. Common Vintage Saw Set Brands And Design Variations
Several well-known brands produced saw sets during their peak usage in the early to mid-20th century. Companies like Stanley, Atkins, and Disston were prominent manufacturers, each offering unique design variations to cater to different user preferences and saw types.
Some saw sets featured adjustable jaws to accommodate a range of tooth sizes, while others had fixed settings for specific saw types. The materials used in manufacturing also varied, with higher-end models often incorporating brass and steel for durability and precision.
8. How To Safely Test And Use A Saw Set On An Old Hand Saw
Before using a saw set on a vintage hand saw, it’s important to inspect the saw blade for any damage or rust that might affect the setting process. Clean the blade thoroughly and check the teeth for uniformity.
