This question already has an answer here:
The only related question I have found here is: What would it be like to use a vibro-blade
But would a swung or thrust blade using a high-frequency oscillation actually improve its combat effectiveness? Would the oscillation provide a meaningful increase in cutting/stabbing capability, and if so, against what materials? Would such an increase translate to improved combat effectiveness?
- Vibrations from this oscillation going back into the handle is no longer a problem.
- We can somehow generate these high-frequency oscillations in a sturdy material.
- The weight is somehow reasonably able to be wielded for function; i.e. with not much more difficulty than the 'non-vibro' version.
- Power supply isn't an issue.
Edit: I am not asking how to make one or how it would 'feel' but if it would be any more effective than a standard swinging blade of the same weight, sharpness, and curvature. The question I linked to never seemed to address this; if it did, I missed that entirely or I wouldn't have asked this question. Looking over it again, I still don't see the answer to my question.
Oh, and "They'd get shot before they could use it." isn't helpful to this question. There are plenty of ways that melee can still be important in fiction.
