OK (why did I ever answer GTAsteel's question about tang pins
) here goes. Assuming also the following: equal amount of force used to flip both handles, and the dimensions and shapes of the handle are the same. Using the basic Vertical opening as our guide:
Step 1: Swing bite handle outwards. The Ti handle will travel faster, because it has less weight, up to the point of tang pin engagement. At the point of tang pin engagement, where the bite handle now levers the blade out, to the handle hitting the back of the hand, the Brass handle will travel that leg faster, because the heavier mass has more stored energy to exert on the tang pin and overcome the resistance of the balde from traveling from rest. Once the handle hits the back of the hand, both handles are at rest.
Step 2: Swing bite handle downwards. Here there is no tang pin engagement, so the blade doesn't come into play. They should travel the same. The Ti handle again will travel faster initially because of it lighter weight, but centrifugal force will accelerate the Brass handle faster towards the end of the swing. It should even out.
Step 3: Swing bite handle upwards into the palm of the hand. Here, the results should be the same as Step 1, again because of the tang pin engagement and the stored energy behind it.
Tomorrow we tackle the Helicopter (yeah right...
).On a serious note. The additional weight of the Brass handle is advantageous only when you rely on the handle's swinging momentum to carry the bali into another position. You'll letting the energy of that swinging mass help you rotate the handle in your hands, with less additional input from you. If most of your manipulations have lots of positions where the handle comes to rest (like a ricochet), that advantage is lost. It now becomes a disadvantage because the amount of energy it take to restart that handle will exceed the T1 handle over time.
When it comes to ariels, I don't have a clue, as I never thought about it. And I'm not about to conduct a scientific study by doing the same moves 100 times each to collect a sample. I don't want to bleed that much.
