In assembly I tend to do the same task typically for several days in a row. Sometimes the repetitive use of tools can really wear on my fingers & hands. I was trying to figure out a way to help make the swivel knife more user-friendly and came up with the idea of trying pencil grips to help cushion the tool so that it's not as uncomfortable to hold. Due to the rubbery nature of the gripper it is cushioned and makes it more user-friendly. Wasn't sure which "waste" to use because it's more of a safety/wellness option. Hopefully this all makes sense. Thank you!
