A scratch awl is a woodworking or general shop working hand tool that is used to scribe or “scratch” marks or lines into various surfaces. It is usually about 6″-7″ in length. It’s also used to start or punch and pierce holes (such as before drilling) into materials. As a preparation tool, the scratch awl tool is most often used as a pre-etcher before making a more complete or deeper cut. The line it makes, creates a groove or track mark for larger tools to follow.
What’s a scratch awl made of?
This handy tool is comprised of a smooth handle or knob on one end, and with a rounded, metal shank or spike on the other end. The shank end or bar is about 3/16″ in diameter and is sharp at it’s point. The handle can be made of hard wood or plastic. Some manufacturers make the tool one solid piece, made of steel. The handle end then, can be coated with rubberized gripping material. It may also be reinforced so that the awl can perform light “hammering” functions when needed. Other heavy duty scratch awls come with enlarged wooden handles, allowing the hand to get a full grasp on the tool. This ensures more power and comfort when using on harder material.
Marking awl prices range from just under $2 to $20 or so, with most falling the 5-$10 range. It’s important to get one that is quality, i.e. the hardness of the steel used so that it will last. One common complaint is that the tip of the awl can bend or become dull with usage. These are signs of an inferior quality, and occurs in cheaper models.
