Here's a short clip of an introduction to Pekiti-Tirsia Kali knife-tapping principle during our Magkatipunan Sa PTK-Peninsula event last year. I am assisted by my friends Joe and Buddy.
This is the first time I've taught this drill to a large group of students and of different experience levels. I was introducing everyone to the principles of bisecting line, primary and secondary tapping, and more importantly the 180 degree side-step, which are all critical in teaching a student to get offline and away from an incoming attack. For obvious reasons I couldn't cover every little detail during this segment.
The other aspect we emphasize with students is to actually strike the weapon arm using our hand blade principle as you evade and re-direct it away from you. Once the student is competent in executing these movements in a free-flowing manner with complete control, we then progress to a faster tempo, adding more force into the knife attacks, as well as adding other options like counter offensive strikes, traps, locks, takedowns, and disarms.
At this foundational level it's not advisable to teach knife-tapping as self-defense and it would be irresponsible for anyone to do so.
