Greetings all, for ExtraBaconPlease' inquiry...a SHTF scenario of unknown origin, with no guns and only one blade for combat among any Bussekin we own, I would choose my custom shop satin Waki. My reasoning is as follows, I immediately ruled out all my smaller blades...a few Ratmandu variants, a SYKCO skinner and 411, as insuffient for any major combat due to their size.
The Rucki, Waki and AK47 are all fine choices, as are many of the others mentioned by our fellow HoRaDo's (Hog-Rat-Dogs

) Kukri's are primarily choppers with little thrusting ability, and the larger swords are simply too slow in-hand for my consideration even if I owned any Busse versions, and with a little over two decades of experience with several Filipino martial arts systems, I prefer a wide range of capabilities in my combat blades.
The Rucki is well suited to concealment under a large coat if necessary, and has fine balance and both slashing and thrusting ability...but is ill suited for parrying attacks from larger weapons such as Baseball bats, metal pipes, a length of steel rebar...or other improvised weapons thugs might carry openly in a lawless situation.
The AK47 has little concealability, but the extra length, mass and a two handed grip enable more powerfull attacks and more efficient defense against larger weapons...BUT, it's a little slower to attack with and recover from for the next blow.
The Waki is a nice comprise between the two, compact enough to wield in tight spaces, with a two-handed grip to help parry larger weapons and due to a peculiar trick of physics, is better balanced than either the Rucki or the AK47 and is faster to wield one handed and recover from the swing for the next strike.
I came to these conclusions from live cutting practice with both the Rucki and the Waki using tatami mats (Rolled bamboo matting used to simulate limbs), and "Ghost" cutting practice with the AK47. As soon as I give my AK a satin finish, I'll be turning her loose in practice as well!
My two cents worth at any rate, I hope you all had a great Thanksgiving...and that you and your families enjoy Christmas and have a healthy and prosperous new year! :thumbup:
