This bell will make a bad sound. But maybe its fun to drink with it.

After incidents in the UK last week, i wanted to make sure my car was fully equiped in the event of an accident.

Here is a first design of a safety hammer, comprising of a blade to cut a seat belt and a hammer end to break windows.
PLEASE NOTE, I HAVE NOT ATTEMPTED TO USE THIS OR TEST IT.

The hammer is made using available tools and parts so this should be easy to manu.

This is the 4th revision, and i can see something that i want to make better - angle of the blade and a slope to allow the material being cut to easily slide out of the slot.
Any other updates you wish to mention and i will update.

Here's a model of Mjöllnir, Thor's Hammer ( secure.wikimedia.org/wikipedia/en/wiki/Mj%C3%B6llnir ), scaled to the same size as an artefact found at Bredsätra in Öland, Sweden. Not quite up to the same standards of workmanship, but it'll do for a start. There is a hole for a cord in the handle, and the SCAD file is parametric so you can easily change it's size and shape without altering the size of the cord hole.

Here is proof that high performance composite (powder) 3D printing can provide very real usable parts.

We printed this hammer I designed and finished it using our Resin-X© thermoplsatic resin. As depicted, we have driven over 100 3.5" nails into solid wood for demonstration.

Note that there were hardly any marks on the head, nor were there any chips after all that use.

Yes, it may still be brittle, but it takes a good beating!

For those whole like to ban things, this is a printed speldge hammer with the word BAN reversed out of the face.
