Bostitch Office EZ Squeeze Heavy Duty 3-Hole Punch for Home Office & School, 40-Sheet Capacity, One-Touch Reduced Force, Sleek…

Across the reviewers we read, the Bostitch EZ Squeeze HP40 is the most consistently recommended manual heavy-duty pick. The Amazon verified-purchase base sits at 4.8 across more than 12,000 ratings, and Walmart and Staples verified-purchase reviewers specifically credit the long-lever 'EZ Squeeze' geometry for letting them push close to the 40-sheet rating without two hands or body weight. The all-metal construction is the other recurring theme — buyers contrast it favorably with plastic-bodied heavy-duty punches that bend at the linkage.

Reddit's heavy-duty-punch discussions on r/BuyItForLife and r/notebooks generally endorse this category of reduced-effort lever punch, though commenters caution that any consumer punch's heads will dull with sustained heavy use, and that 40 sheets of 20 lb paper is the realistic ceiling — heavier card stock should be punched in smaller batches.

The disagreement worth surfacing: a minority of retailer reviewers complain that holes sit slightly further from the edge than on their old desk punch, which can crowd text near the margin. For typical binder use this isn't a problem, but if you're punching pre-printed forms with tight margins, test one sheet first.
