Unscrew the two parts of the handle, insert the awl shank into its seat and set it to the desired length, then carefully screw the parts back together until the shank is firmly locked, without forcing. Check that the awl is firmly fixed with no play before using it. Hold the handle in your palm, place the point on the material to be pierced and push firmly, turning slightly, until it pierces. To change the awl, unscrew the two parts again, gently pull out the shank, insert another one and screw back together. Do not use the handle as a hammer and do not lever with the blade, so as not to damage the wood and the ferrule. After use, check periodically that the two parts are firmly screwed together and store the handle in a dry place, away from damp and heat sources, to prevent the wood from cracking or warping.
