Explanation:
The major difference between the 66 and 110 Block punch-down tools, traditionally used in telecom and data network wiring, lies typically in the blades (Option 2). The 66 and 110 tools are designed for different types of blocks. The 66 is mostly used for telephone wiring while the 110 is more commonly used for data/computer network wiring. The blades vary in the way they cut and terminate the wire into the insulation displacement connector slots of these blocks. The 66 block tool has a single blade and the 110 block punch-down tool normally has a blade on each end. The Impact level (Option 1), tool make (Option 3) and color (Option 4) may differ between specific tools, but those are not categorically differentiating factors between the 66 and 110 tools.
