Using the Klein 44005C knife is a breeze. To open it, simply use the reversible thumb stud with one hand. The lockback mechanism will keep the blade open securely when you're using it. When you're done, close the blade carefully. Make sure to keep the blade away from children. For maintenance, clean the blade with a dry cloth after each use. If the blade gets dull, you can sharpen it as it's sharpenable. Store the knife in a dry place to prevent rust and damage. This knife is designed to handle tough jobs, but avoid using it for tasks it's not meant for, like prying open hard objects.
