I would like to talk about the sweet spot for power cuts

I saw people using large powerful pieces last weekend and, while they were certainly effective, there was room for improvement.


The tip is for speed. I think everybody understands that. That will get through flimsy targets and this is why machetes are made so light, so they can achieve speed easily for cutting grass.

But for powering through a 2x4, you need to be in the power zone and that's farther back.

I have labeled the center of percussion, the sweet spot, and the center of gravity on this K18.

We added the pommel to the design to move the center of percussion back where it is so the sweet spot would be in a better place for chopping. That's why it's there. And it adds power to the sword, this is why it is so powerful for its size.

A hit on the center of percussion makes a very dead solid thump in the cut. And it's not a bad place to hit.

A hit further out towards the tip, the sword will rotate around that center of percussion so you are losing some of that impact energy to rotational energy, and it is trying to make the sword rotate around the cut out of your hands, putting your fingers in tention. This is wasted energy.

The sweet spot is directly behind the center of percussion. This is an area that will encourage the sword to rotate up into your hands where the weight and momentum of your arm add additional power into the cut.

I saw some cutters last weekend who were a little bit too far towards the tip, probably because that's where things like machetes work best, but not a powerful sword like this.

Just FYI.
