I think it isn't the energy it's the peak of the impact force. A stab impact with the weight of the arm is softened by the palm of the hand as it backs up the tool. A swing of a nut tool (hammer-like) over 3" would give a reasonable peak force if you hit the target but the swinging end is only a few grams. There is a huge discussion of the physics of this over at Mountain Project:

LittleHammer is 130g, the impact weight is over half of this and accelerates pretty fast when released. I had some engineer students offer to model the forces but haven heard back yet. It was trial and error for me, the second prototype weight didn't have enough grunt so I upped its mass.
One of our backers just pulled out of the limited "get LittleHammer rolling special" so there is one available: AU$70 with free postage world wide. Grab a good deal!
