Step 1: Handaxe Definition. Handaxes are significant Lower Paleolithic tools. They are classified as core tools, created by striking a stone (the core) to fashion sharp edges. Step 2: Evaluation of Tool Types. - Option 1 (Flake Tool): This category involves tools made from detached chips (flakes), distinct from shaping the main stone. - Option 2 (Core Tool): This aligns with the handaxe's construction method: direct shaping of a stone core. - Option 3 (Iron Tool): Handaxes predate iron technology, being exclusively stone implements. - Option 4 (Blade Tool): While sharp, handaxes do not fit the typical characteristics of blade tools. Step 3: Classification Determination. The handaxe is a core tool due to its fabrication process, which involves shaping a stone core to produce cutting edges. Final Answer: \[\boxed{\text{The correct answer is (2) Core Tool.}}\]
