If you are working with a lot of vinyl film then this cuff is a godsend. It stops you from having to stop work to look for your tools as they are always in a handy place. You can imagine how annoying it is if you have to stop putting up some wallpaper, get down the ladder, all just to get your cutting knife.
The cuff has a hook and loop closure, bands to hold tools, and a magnetic area to hold metal objects. I wouldn’t be without it.
