Wow!!
I'd say if anyone doesn't already have at least one fatty at over .3" thicc, you absolutely
need this.
Didn't understand the appeal for a long time until curiosity finally got me to pick up a thick-cut BG FSH a while back. True, it wouldn't join me on an ultralight backpacking trip, but I'm fine with that. Having it on hand around the yard or next to the woodpile is enough for me. Just a beast.
For reference, the fat BG FSH is spec'd at .3125" and weighs ~28oz* (still under 2lbs) with a blade just over 8" long. Probably not a bad starting point for guesses on the Mega Ratweiler.
*analog scale measurement. Batts on my digital scale are dead atm.
