Sometimes you need to take a more delicate approach when you're trying to bend some contraption to your will by punishing it with a hammer...

InstaMorph to the rescue!

Instructables sponsored a Build Night at Urban Workshop, and supplied us with InstaMorph to play with -- this is one of the ideas we came up with ;-)

Step 1: Supplies

A piece of InstaMorph sheet (see Making Flat InstaMorph Sheets) works well for wrapping the hammer head.

Step 2: Covering the Hammer Head

Place the InstaMorph sheet in hot water until it starts to turn transparent, then remove.

Put the hammer head on the center of the sheet, then fold up the edges of the sheet around the head.

Wait until the InstaMorph has cooled (turned solid white).

Thump that contraption!
