衝壓成形平板 — 實心鋼，22個拋光凹槽，珠寶工作台工具

The steel block has a satisfying heft that keeps it stable while I hammer silver sheet into the polished depressions. I’ve used it for copper too, and the smooth finish leaves no scratches on the metal.

The 22 polished depressions are exactly the variety I needed—I’ve been sinking copper and brass without any snagging, and the steel holds its mirror finish even after a few hammer passes. It’s heavy enough that it doesn’t shift on my bench, which makes the whole process feel more controlled.

I've been using this flat block for a few weeks now, and the 22 polished depressions make it easy to switch between different dome sizes without changing tools. The steel construction handles silver and brass sheets beautifully, with a clean, consistent finish every time.
