Tanto Dori

Aikido Weapons Tanto Tori ...

The application of Aiki in the Tanto taking technique demonstrated in the video is analysed below. 


Analysis

At a time of 1.03 Uke attacks with tuski. Tori side steps and makes contact with Uke's hand/Tanto. Tori induces Uke to apply Aiki by Tori slightly lowering his body to apply downward pressure on the Tanto causing Uke to pull upwards on the Tanto. The action of Uke pulling upwards induces him to reverse the muscle torque about his front foot ankle joint, to straighten his body, causing Uke to become unbalanced to the front by his forward momentum. 

Tanto Dori - Knife Taking (Slash and Stab)

The application of Aiki in the Tanto taking technique demonstrated in the video is analysed below. 


Analysis

At a time of 9.56 Uke attacks with a slash and stab. As Uke stabs, Tori induces Uke to apply Aiki by appearing to block Uke's knife arm, with his left arm, causing Uke to reverse the muscle torque about his front foot ankle joint causing Uke to become unbalanced to the front by his forward momentum when Tori blends with the stab instead of blocking it. 

Tanto Dori Yokomen Uchi

The application of Aiki in the Tanto taking technique demonstrated in the video is analysed below. 


Analysis

At a time of 00.25 Uke attacks with Yokomen Uchi. Tori steps forward to block the attack and induces Uke to apply Aiki by applying an atemi to Uke's face, causing Uke to reverse the muscle torque about her ankle joint of her rear foot to minimise the impact of the atemi. Consequently, Uke becomes unbalanced to the rear due to the contact reaction force due to the block. 


At a time of 3.49 Uke attacks with Yokomen Uchi. Tori steps forward and induces Uke to apply Aiki by appearing to block Uke's arm. To overcome the block, Uke reverses the muscle torque about the ankle joint of her front foot causing her to become unbalanced to the front by her forward momentum when Tori blends with Uke's attack instead of blocking it.  



Tanto Dori Shomen Uchi

The application of Aiki in the tanto taking technique demonstrated in the video is analysed below. 


Analysis

At a time of 2.43 Uke attacks with Shomen Uchi. Tori steps forward and induces Uke to apply Aiki by appearing to block Uke's arm. To overcome the block, Uke reverses the muscle torque about the ankle joint of her front foot causing her to become unbalanced to the front by her forward momentum when Tori blends with Uke's attack. 

Aikido TANTO DORI, knife defense, chudan tsuki KOTEGAESHI

The application of Aiki in the tanto taking technique demonstrated in the video is analysed below. 


Analysis

At a time of 0.00 Uke attacks with chudan tsuki. Tori steps forward and induces Uke to apply Aiki by applying an upward atemi to the attacking arm. To minimise contact with the atemi, Uke reverses the muscle torque about the ankle joint of her front foot causing her to become unbalanced to the front by her forward momentum.
