1. Binding Capability: Binding strength determines professionalism.
Core Indicator: Maximum binding capacity (not average)

For daily office use (≤20 pages): Choose a standard desktop model (such as the Kokuyo HIT model), balancing portability with basic needs.
For financial/archival use (20-50 pages): A heavy-duty lever-type model is essential (the Deli 0675 uses a dual-lever booster, increasing binding force by 40%).
For design/printing needs: Look for an all-metal industrial machine (such as the Swingline 747, which can bind 300g coated paper).
Avoidance Tip: Beware of inflated specifications! When measuring, increase the nominal page count by 10% (e.g., 20 pages marked, measured 22 pages). Verify for bent staples or paper jams.

2. Needle Type Compatibility: A Consumables Trap Ignored by 90% of Users
Mismatched stapler specifications can lead to frequent staple jams. The three major staple types must strictly match:

Needle Type Code Application Compatible Model Examples
24/6 General Documents (≤10 pages) Most Mini Staplers
23/8 Bids/Reports (≤30 pages) Scott J13 Series
23/13 Contracts/Catalogs (≤50 pages) MAX Heavy-Duty Stapler
Industry Truth: Japan’s PLUS patented “Anti-Stick Guide” technology uses a U-shaped track to correct the stitch angle, reducing the stitch jam rate to 0.3% (industry average: 12%).

III. Ergonomics: A healthy investment in pressing 300 times a day
Long-term use of a low-quality stapler can lead to carpal tunnel syndrome. Focus on three key features when purchasing:

Effort-Saving Structure:
Lever-Type > Spring-Type (over 60% less effort)
Preferably, a grooved bottom design (such as the Maped OP360, which reduces finger force distance by 30%)
Anti-Slip Grip:
Soft Rubber Wrap > Hard Plastic (2x the Friction Coefficient)
Grooved Finger Design Reduces Hand Movement
Press Feedback:
High-Quality Springs with Clear Rebound (4-6N Resistance is Optimal)
Avoid a Loose Feeling (Waves > 0.5mm are considered unacceptable)
IV. Special Features: The Hidden Value of an Efficiency Multiplier
Targeting Advanced Needs in Specific Scenarios:

Stitchless Stapler (Patented Slit Binding)
✓ Suitable for confidential documents (hospital records/legal documents)
✓ Annual consumables cost savings of 37% (measured data)
✓ Rotatable stapler head
✓ Horizontal staples for temporary binding, vertical staples for permanent filing
✓ Recommended MAX HD-10FL with rotation damping technology
Tabletop organizer
✓ Built-in staple magazine capacity > 100 staples (eliminates frequent refills)
✓ Magnetic bottom design prevents spillage (such as the Kokuyo Campus series)
V. Durability Test: Insight into the Survival Principles of Internal Structure
Cost-effective staplers often have fatal flaws:

Spring Material: Music steel wire > Ordinary carbon steel (5x shorter lifespan)
Stamping Module: Integral precision casting > Assembled components (200% increased deformation resistance)
