Sheet Capacity: Match the stapler's maximum capacity to the thickness of the documents you regularly bind.
Adjustable Settings: Look for models with adjustable staple depth (how far from the edge the staple is placed) and force settings, which are useful when working with varying material types.
Staple Compatibility: Heavy-duty staplers often require specific staple sizes (e.g., 23/6, 23/13, etc.). Ensure the stapler is compatible with the gauge and leg length required for your most frequent projects.
Jam-Resistance: High-quality models include features that keep the tool functioning smoothly, saving time in busy work environments.
