What kinda crazy world scenario do you think this would be good for? In my opinion if your blade is gonna do double duty, EDC/SD I would prefer an overbuilt knife and certainly if weight is the consideration, at least go with CF or even G10. Plastics like "cheaper" FRNs serve great as an EDC for normal day to day cuttin' or slicin' but when it comes to SD it better be a FB for dependability and speed.
I gotta ask the OP what scenarios are you exposed to? How often and what in particular have you been exposed to if you don't mind me askin'? I'm not talkin' about the GTA fantasy video game scenarios, I mean what city violence or type of job do you have where you safety is a concern and you feel a knife is a faster, better alternative to a pistol or revolver?
Sometimes I think younger people are preparing for TEOTW & the SHTF scenarios where the dead will rise and the Walking Dead become the norm so everything must open fast and be big and terrifyin' when used to deanimate the living dead.
To the OP, do you really think that replacing the Buck with the same knife is a bad choice? Keep n mind that it might be something else other than a refrigerator it hits next time. The method you describe sounds inherently dangerous and uncontrollable, can you better describe your method or maybe post a video to better illustrate your method.
