There are two basic "Schools" of using a Balisong in Self-defense:
#1 Use every part of that knife, including the handles as flails/impact weapons.
#2 It's used as a knife, by all means, learn to open it a dozen ways, but don't use it as a flail, etc.
Now, I'm in Group #1.
Both Group #1 and #2 use it as a handheld IMPACT WEAPON, but Group #1 takes that farther and uses it as a
Flail.
So, both groups use it like a Palm Stick but the major difference is using it like a flail, for that type of striking.
If you use a BM42 for an Impact Tool, it will work for that, as well as anything else a pocket stick will. It is a piece of metal.
As a flail, it is not, except as a distraction...
Even a 44, 45 or 48 [BM] will knock the snot out of you.
A Samson Custom will bust your knuckles if you get hit with it.
This promises to be more of an all-around Balisong instead of something more geared to high speed manipulations, etc.
