Corona FlexDial® Adjustable Bypass Pruner Earns International Acclaim

Industry responds to FlexDIAL® taking the guesswork out of choosing the right size pruner

(Corona, CA) One size does not fit all when it comes to hand tools like pruners. A common mistake gardeners make when buying pruners is to opt for the largest cutting capacity available, regardless of the size of their hands. A pruner designed for larger hands can be uncomfortable, difficult, and tiring for someone with smaller hands because when the cutting blades are wide open, the spread of the handles is too big to handle, while those with larger hands may not take full advantage of their greater leverage.

Corona's patented FlexDIAL® Adjustable Bypass Pruner (BP 4214D) is designed to maximize efficiency during pruning based on hand size. The adjustable dial lets you customize how wide the blades open to fit the branch you're cutting. This ergonomic innovation helps you tackle repetitive chores like deadheading while relieving hand fatigue.

With its revolutionary design, the FlexDIAL® Adjustable Bypass Pruner has received worldwide acclaim for this gardening innovation:

  • Rodale’s Organic Life Magazine "Top 100 Garden Innovations"
  • This Old House  “Top 100 Lawn and Garden Products”
  • International Design Excellence Awards (IDEA) Finalist
  • UK’s DIY Week Awards 2019 “Garden Tool of the Year” Finalist
