Why am I putting this? besides the obvious lessons?

As Guro Crafty Dog said:

Allow me to add to/rephrase that:

"One is reminded about the dangers of not realizing that EVERY confrontation is potentially a ARMED confrontation."

YES!!!

"Therefore there is tremendous advantage in fighting methods which are the same whether against EH or Knife."

"We are also reminded that grappling with a knife ideally means first ZONING from the possibility of a knife, being AWARE of the knife ASAP, and controlling the knife."

Think upon this.

And I replied:

Agreed, Guro.
It is too bad that the majority of systems do not take into account the attacker being armed, shocking considering the majority were created in a time where many walked around armed !
A system that works from the premise of ARMED rather than UNARMED makes a lot more sense, I mean, if your "defense" works VS a knife there is a pretty good chance it will work VS an UNARMED attack.

Thoughts?
