Re: Ichi no ken ?
Hello, glad to help!
To clarify where this is coming from, I am a 4th kyu learning this from a handful of yudansha in NYC where Sugano did not do a ton of weapons work. My knowledge is seriously limited--you have the real source in Jikou, who came here in summer at the time of Sugano Shihan's memorial and taught at couple of classes that focused on this work.
That said, I did do ichi no ken on Thursday.
Ichi no ken: Teacher and student are in hamni (Sugano goes over this concept extensively in youtube clip) and student breaks maai with a direct ski or thrust. Teacher steps back and anticpates student's next move, which is kiritske (sp?), a strike to the head, by blocking and checking the student's accuracy and maai. Then teacher returns with a strike, which student parries. Teacher goes under the student's blade and skis, student changes hamni and parries again, and then thrusts deeply to force teacher to move back. This kind of resets maai and forces a conclusion. Student raises and presents an opening--sets a trap if you will. Teacher goes for the wrist of student, student steps off the line and delivers a strike to the head. Teacher dies, student lives.
If you are learning weapons from Jikou Sugano Sensei then surely this is what you are learning...
Have fun, this type of weapons training is really inspiring me right now.
