I keep a small "jewelers bench block" (5" x 5" x 1") on my bench, it's small and very convenient. Use it for straigtening pins and inlays and small parts, and for checking flatness of inlays, hammering out silver and brass for inlays, patchboxes and hinges, riveting, etc. very convenient, one of my favorite tools. It's very hard tempered steel, file won't cut it, very flat with nice square edges, made for hammering on, you ain't gonna hurt it. For anything heavier I use my vise. I don't do any heavy forging requiring an actual anvil.
