Questions about this tool

Do I load the fibers before spinning?

Arrange them in the open loop first. Spin once you have the fiber distribution you want.

What distinguishes the 440?

The working end uses the split-arm geometry pictured. The 439 is a separate Y-shaped version.

Does it mount in the vise jaws?

The 440 is a handheld loop tool. Compare the Turbo Spin if you need a vise-mounted spinner for brush making.
