My first set of Tomahawks was purchased from a rock climbing store and I machined them at home to get them to act like "hooks". We were preparing for a deployment where HME jugs were frequent and I wanted something where I could sink a tool into a jug and rip it out reliably. This is the culmination of that effort. These are still able to be smashed into things for hook and line leverage points, but I would caution you against stressing the point too much and bending it. You can always bend it back (I've done it on my first set innumerable times) but it weakens the material each time.
