Are retractable or folding utility knives better?

It depends on the job. Across the reviewers we read, folding knives (like the Fiskars Pro and Klein Flickblade) win on one-handed pocket carry and quick deployment, while retractable metal-body knives (the WORKPRO Premium) get praise for slide-button control and durability on repetitive box-opening tasks. Many tradespeople in r/Tools simply keep one of each.
