The document discusses hand tools used for computer system servicing. It identifies the most essential learning competency as identifying and selecting appropriate hand tools according to task requirements. It groups hardware tools into four categories: electro-static discharge tools to protect from static electricity; hand tools used manually or electrically; cleaning tools; and diagnostic tools. Examples of specific hand tools are given for each category, including anti-static wrist straps, screwdrivers, pliers, wire strippers, tweezers, and diagnostic tools.
