Kempo Guy & Peter,
First , Brother Peter, I just checked out The Hand is My Sword. It is the 1973 revised printing. In the glossary under 'H' it has the term 'hon ken' , next to it is the definition: 'four wrist-fist'. That's all I can tell you about that Peter, but that's where i got it. "Suki", I thought I read it in the same book but I was mistaken. It was another book I have but the name eludes me right now, the definition was, however, 'opening'.
Kempo Guy, I will trace back the lineage for you in Shaolin Kempo to explain the origins of the pinans used, this will clear up any confusion. Okay, Gm. S. George Pesare learned from Sijo Victor 'Sonny' Gascon. Sijo Gascon learned from Sifu John Leoning who was of Sijo Adriano Emperado's Kajukenbo system. Gm. Pesare taught Professor Nick Cerio and in turn Professor Cerio taught Gm. Fred Villari. In the mid 60's when Professor Cerio was still training at Gm. Pesare's school, Gm. Pesare decided to add Taikyoku shodan which was adopted from the system of Mas Oyama. (Oyama was a Korean who studied Shotokan, Goju ryu, Chinese Kempo-the actual kung fu version and judo). This was done to add a form for beginners that would have been easier to learn than Karazenpo's first form which you know as #1 kata. For a reason I do not as of yet know this form was named #1 Pinan, possibly because the Kajukenbo forms at the time were called pinans. That would be my educated guess. Later, after Professor Cerio branched out on his own he used the Taikyoku series of shodan, nidan and sandan from Oyama's system (these were beginner forms of Shotokan origin, called the 'first cause forms' or the student's 'first look' at Shotokan.) and created what he called #2 Pinan, a 'hybrid' which is the seond form in SKK. Professor Cerio than adopted Oyama's versions of #3, #4 & #5 to complete the 5 pinan series. As Brother Peter stated, 3-5 were accurate names for these katas. #'s 3, 4 & 5 go back to the orignal 5 pinan series of Okinawan karate. In Shotokan they are called the Heian series. An interesting note I mentioned in a previous post is that Cerio at the time could not teach the exact pinan series anyway, even if he wanted to, as at the time he was teaching Karazenpo and it would conflict with Karazenpo's original kata series. The reason, Karazenpo's fourth form which is #4 Kata of SKK is actually a modified version of Okinawan Pinan #1. When Master Funakoshi introduced karate to Japan he called this series 'Heian' which I believe stood for 'peaceful shrine' and pinan meaning 'peaceful mind', a form of moving meditation. He then reversed the sequence of numbers one and two because he felt Okinawan Pinan #1 was too difficult to be given first in that series. Perhaps Brother Peter, who is also very knowledgable on this can add something here that I may have missed. I believe Peter and I are on the same page on this part of kempo history.
Respectfully submitted.
