Todays training was about all Bo-Shuriken waza, all stances and distances from 1 to 2 ken. Gyaku uchi is difficult from 2 ken. After that, I started to train Shomenuchi with the left hand from 1 ken. This was very interesting and forced me to really focus on the hand grip as left is my non-dominant hand. Then I followed up with Shomenuchi with two shuriken, one from the left hand and one from the right hand, thrown at the same time from Heiko-dachi and Fuko-dachi. I ended the training with throwing two shuriken at the same time from the right hand, trying to keep them within a 15cm grouping.
I also experimented with the new style bo-shuriken that arrived yesterday. The Shingetsu-ryu bo-shuriken are so strong that they almost penetrate two puzzle mats. I could not practice with the MSR Hanten-daho shuriken as I did not have enough room to move beyond 3 ken.
