Why is a sharp knife safer than a dull knife? Reach for the duller blade because it feels less risky, and you have it backwards. A dull edge is exactly why a dull knife is more dangerous: it slips, catches, and puts you in the first aid kit more often than a sharp one ever will. Sharp is the safer choice, and the reasons behind it are not the ones most people would guess.
Rachel from Ally Safety makes the case across four reasons, from how little force a clean cut actually takes to what happens to the wound itself if the blade does slip. She also runs through the handling habits that keep a sharp utility knife working with you instead of against you.

0:00 The Counterintuitive Truth About Sharp Blades
Rachel sets up why most people believe dull blades are safer and why the opposite is true.
0:47 Reason One: Less Force to Cut
A sharp blade glides through material with minimal effort, while a dull one needs heavy pressure that makes the knife more likely to slip.
1:11 Reason Two: Better Control and Precision
Sharp blades slice cleanly and give you control over the cut, where a dull blade crushes and tears and is more likely to slip dangerously.
1:34 Reason Three: You Handle a Sharp Blade More Carefully
Knowing a blade is sharp encourages safer habits, like cutting away from yourself, staying out of the line of fire, and changing blades before they dull.
2:09 Reason Four: Less Severe Injuries and Cleaner Healing
Even if a sharp blade slips, less force and more control reduce the damage, and clean cuts heal faster with less risk of scarring and infection.
3:06 Final Thoughts and Where to Watch More
