Ergonomic handles and longer lengths improve leverage and reduce hand fatigue during extended work. Tools with mortise hooks, slot designs, or secure grip heads provide precision during installation and adjustments. Budget-conscious buyers may prioritize versatility across multiple window types, while professionals may prefer heavy-duty options with longer lifespans. Finally, verify that the tool’s length and fit match your specific window model to ensure safe, effective operation.
