That vise should have a wood handle. The original looked like dowel with elongated knobs on the ends. As a wood vise it never needs a lot of torque on the handle. I had to make a new handle for mine but have still to do the end knobs. My wood turning skill is not quite there yet.
I like wood handles as well. A simple design is a piece of dowel with rubber cane tips on each end. They are quiet, and don't get cold like steel pipes do.
