The first blade my parents let me have was a tomahawk. I still have my original, and I love it dearly. Recently I was playing with it, and I thought to myself, "I sure would like to do some aikido with this." It just so happens my favorite training knife producers, also make tomahawk blades for a inter-changeable system they have. So I ordered the blade and mounted it on a tomahawk shaft I had in the garage. It was tough mounting the blade right, but I think the couple nights of tinkering with tools paid off. She is solid and sexy and itching to start training in the dojo. Sadly I only have one more day in the dojo before I go on my budo walkabout.
