Some more thoughts on thumbscrews.

Knurled screws are attractive but can be uncomfortable if they must be gripped tightly to do their job. If only for occasional, delicate adjustments, like a micrometer barrel, they're fine but for frequent adjustments requiring a firm grip (e.g. the handles on a threading die stock) they can be uncomfortable.

One solution is to run a file over the knurls after they've been formed. This will knock the tops off the little pyramids that form the knurl and make it more comfortable to handle.

For beefier stuff I prefer fluting. It provides a firm grip and is much easier on the hands. An example is my tripod quick release handle...
