train hard and stay safe!
If we're talking MBC then I'm a Janich man through and through. To me the gunting looks weaponized and martial which means a freaked out jury when it comes to the inevitable trial phase of edged weapons use in self-protection situations.
If I need a blade to protect me and mine I'm gonna open it as soon as I can, I'm not going to willingly use a knife as a blunt force weapon. I'm either justified in my use of lethal force or I'm not, that's for the jury to work out, but if I decide to draw a knife and use lethal force I'm not gonna goof around trying to kin-op the thing off of the perp who is attacking me. In the same vien I wouldn't try to draw a gun defencively and then try to use it to pistol whip the perp, I'd shoot the fool.
I will allow that the ramp can be used to get the blade open during the truth of the moment rather than planning on kin-opping off the bad guy. But if yer unarmed in extreme close range both hands would better be used for fighting rather than trying to fight with one hand and draw a blade with the other. Getting a blade into play takes a bit of time and space and if your battle plan includes drawing and presenting a blade while already in the ring of fire I hope you also train grab defences.YMMV
