In Pekiti Tirsia (as taught by Tuhon Bill McGrath) there is quite a bit of empty hand material. The new student is started out on a block of material called "Tempering & Kickboxing". This really has nothing to do with kickboxing (ring, gloves, rounds etc.) but is just some basic modified boxing, other hand weapons, kicks, footwork, basic combinations, counter-offensives, etc. to get the student some basic tools, timing, etc. Along with some arm conditioning exercises - hence the tempering.
The next block is what Mr. Lamade made reference to. This is the Abcedario de Mano - which are twelve small 'forms' that contain twelve strikes each. Each form accentuates a certain striking tool, i.e. - slap, fist, elbow, forearm, kick. Once the form is learned, basic applications of each strike are learned. Then one is supposed to mix stuff up and explore the applications more deeply, and under less than ideal circumstances....
Afterwards one learns Pekiti de Mano. This is a set of five entrances against twelve different attacks and a set of twelve takedowns, locks, and throws. The overall theory being that you use the entrances and finishes from Pekiti de Mano with the Abcedario de Mano material as filler. Of course, each block works well on its own as well.
Also there are two levels of empty hand vs. knife. Level 1 vs. sak-sak (hammer grip) and Level 2 vs. pakal (icepick grip). These contain parrying drills, blade reversals, strikes, takedowns, disarms etc.
And if that weren't enough, there are empty hand vs. stick versions of all the stick vs. stick Pekiti Desarma techniques. Which equals out to be 30 disarms, 30 counters, and 30 recounters. The same can be said for the double stick vs. double stick disarms.
Lastly there are some really sweet empty hand applications of some of the drills from 64 attacks, double knife, and espada y daga.
I hope this helps.....
