Carpet installers usually wear knee pads, but a Pennsylvania carpet installer turned inventor has taken it a step further. Mark Legenstein, who installed carpet for years, invented "Knee Blades" to make the job easier for anyone that works on all fours.
"Knee Blades" allows them to roll easily on their knees. Legenstein said it was a dream that took 50 prototypes and plenty of hard work. Mark's invention can be found at some Lowe's stores, but call first to make sure your local store stocks it.
