I have a craft knife that I’ve used for a number of years now and the rubber grip stretched and ripped and became unusable. I’ve been using it a bit without the grip, however I felt as if I didn’t get enough of a pushing force on it without the grip and it frankly felt a bit unsafe.
I modeled a simple grip after another pen I have. Also, this particular knife design is prone to rolling, so I wanted to make an anti-roll attachment. Again, a very simple design based off of another hobby tool that I have.
All the parts were printed in about an hour.
Everything fits the handle nice and snug. Time to put the upgraded knife to good use!
