The War Hammer, -not to be confused with a nail hammer (unless you're going to war against a bucket of nails) - was used as a close combat weapon.
The hammer was made hard and out of metal so when fighting against a sword or other long weapon like it, it would simply bounce off rather than cut the handle.
Against armor, the War Hammer was very handy. Unlike a sword that would simple ricochet off the armor, the War Hammer was sturdy, and strong enough to land a deadly blow to the helmet.
*Disclaimer: I have done extensive research on each of these weapons. I am aware that there are many different versions of each of these weapons. I am not trying to spread false information. If you know and can prove any information wrong, please let me know and I will fix my errors. I have at least three references for all research on the weapons I will discuss through the challenge.
Don't forget, on May 3rd we are linking up to post about our thoughts, comments, concerns, and what we love about this years A-to-Z Challenge! You can read more about the reflections posts HERE!
