At a recent class, we were working on Pekiti-Tirsia's "3d Hand" principle against multiple knife thrusts. The usual plan is to render the opponent blind, or otherwise knock him senseless and then range-out in an explosive manner to "welcome" the next opponent.
For this particular class however, I decided to show how kuncian (locking) from Silat Kuntau Tekpi could be applied against a knife attack. After waylaying the knife, instead of ranging-out you immobilize, then lock him down from his core.
Some of the newer students were seeing (and feeling) Silat Kuntau Tekpi for the first time.
The next day, one of the students sent me the following note:
After bugging you for awhile to demonstrate Silat Kuntau Tekpi to me, now that I have seen it, I am almost sorry I asked. I can only describe this martial art in one word, cruel.
I have been exposed to joint locks, but it appeared that almost every technique you demonstrated worked on destroying the entire body rather than focusing on a single point.
The interesting thing about this was the simplicity of getting the opponent - actually victim - into the positions you want them in. Unlike some of the grappling arts I have seen, most of these moves happened without any setup, you just went directly into them.
After seeing this I must say that I would rather be beaten with a stick or cut up with a knife than face a Tekpi practitioner and have my body broken in this ferociously painful manner.
With all of this being stated, I will say that everything I was shown was brutally effective. If a person wanted to end a fight immediately in such a way as to make even the onlookers wince in pain, then this is the art to use.
Just my thoughts on what I witnessed.
