Here’s a refined summary of the Project Farm video testing various utility knife blades:

⸻

🔍 What They Tested
• Brands compared: DeWalt Carbide, Lenox Gold, Stanley, Milwaukee, Irwin, Craftsman, Tajima, OLFA, Fiskars, and others.
• Performance metrics:
• BESS sharpness test (initial blade sharpness)
• Cardboard cut test (distance until dull)
• Drywall erosion
• Copper pipe abrasion
• Staple hitting toughness

⸻

🏆 Top Performers

1. DeWalt Carbide Edge
• Outstanding sharpness retention across tests
• Easily outperformed standard steel blades (cardboard, drywall, pipes)

2. Lenox Gold / Bi-metal
• Ranked second overall
• Very strong edge retention and durability

3. Stanley & generic blades
• Mid-range performance, but good value

⸻

⚙️ Why DeWalt Carbide Rocks
• Features a tungsten carbide edge laser-deposited on a steel backing
• Provides 10× longer edge life than typical blades  
• Harder edge resists dulling very well, though slightly more brittle
