You can identify when a tool needs re-sharpening by observing its performance; if it struggles to cut through materials, requires increased force, or produces ragged edges instead of clean cuts, it's a sign that the blade is dull. Additionally, if you notice excessive heat or smoke during use, or if the tool has become less efficient than usual, these are clear indicators that re-sharpening is necessary. Regularly inspecting the tool after use can help catch these issues early.
