Martelo de dupla extremidade - Fretz HMR-7

I've been using this to smooth out some tricky copper pieces, and the wide flat plastic end really helps avoid those tiny dents. The fact that it comes with nine different inserts means I can switch from planishing to embossing without grabbing a different tool.

I was skeptical about plastic ends for metal work, but the nine interchangeable tips let me switch from planishing to raising without changing tools. The hammer feels balanced in my hand, and it's nice not having to worry about marring the surface with every strike.

The interchangeable plastic tips are a total game-changer — I swapped between the planishing and embossing shapes mid-project without ever worrying about marring the copper. It's like having a whole toolbox of hammers in one handle.
