I was looking at them and started thinking about the swing motion each presents. So which is best from a physiological perspective on the entire swing?
As I look at them I see that their shapes are all variations of a curve/line. The parang sweeps away. The machete is a straight line. The kukri sweeps forward. They each give different swings as it relates to wrist position.
Looking at the entire motion of the swing I see:
The parang starts with a comfortable wrist position and generates the most initial power since its swept back design places the edge farthest from the target at the beginning of the swing. But the end of its swing compromises the wrist position the most with over extension for the very same reason. The user has to over extend their wrist to make contact with the target. This loses control, actually loses power due to excess bleed off, and can harm the joint.
The kukri is opposite from the parang as it starts with the most over flexed wrist position which harms the joint. It also generates the least initial power since its swept forward design places the edge closest to the target at the beginning of the swing. But the end of its swing is the most favorable for the wrist for the very same reason. The swept forward design provides better better control, a gain in power, and the most favorable ending wrist position.
The machete holds the middle ground as the wrist is neither complety flexed or over extended through the entire swing. It maintains better control than either as the wrist position is not compromised. It generates less power but loses less power as well.
Over all the machete is the best at preserving control and total range of motion for the wrist. It ends up with a neutral power generation and ending of all three, but I'll take control over power any day.
Comments? Ideas? Thoughts?
