What's the safest utility knife for warehouse or retail use?

Self-retracting 'safety' knives like the squeeze-handle Cat 240071 are designed specifically for environments where the blade must retract the moment the user lets go. Reviewers note this trades convenience for safety - they're slower to use, and one r/CrappyDesign thread we read complained the auto-retract can trigger mid-cut. They're a fit for compliance environments, not necessarily for tradesmen.
