Your entire pick fits in there? Or you ground them down to fit? I too like the handle, much less slipping and better "feel" IMO.
You can find the handles at any home improvement store (like Home Depot/Lowes in the USA). You can also find them at art supply stores, although there is a good chance they'll be more expensive. I've never seen the handle alone, only with blades so that's likely the only way you can find them.
