This is an original construction invented by the photographer (Marcus Gun). This is the only photo, so it’s not quite clear what it looks like from the front.

I call this “square arm tie” the Japanese tie, because it’s so popular in Japan. What’s interesting about it, that it’s not tight at all, but it’s inescapable. You can not pull your hands out of the cuff, because:

• you elbows are hold in place by the horizontal rope (or link in this case)
• you can not lower your hands, because of the vertical rope/link

Even if you have a knife (let’s think of a traditional rope version), it’s very (unbelievable, but true, you have to try that!) very difficult to break free (especially without cutting yourself).

But what about self-bondage possibilities? Let’s brainstorm it.

• You need soft elbow cuffs with D-rings. I do not believe in rope here, because it may cut the blood circulation
• The wrist cuff should be wider than two wrists together, because you insert more than just wrists into the cuff. You literally wedge your arms from both sides
• You can make a similar harness or use a karada
• I would connect the two harness parts together, but you may lose the adjustability

• 

  
  

  If you use a karada, a ring connected to the neck rope (behind the neck) will become a top anchor point (see this page)

• Now you have 4 (karada) or 5 (on the photo) points to pull together
• A cinch noose can be used, but as I said earlier, it’s very difficult to cut any ropes (see hands location)
• Or you can use a simple rope loop, thread the pull end through the SRD connected to your knees (there is no much flexibility in the back, severe tie will arch your back leaving very little space for any movements, escape will be very difficult)
• I doubt you will be able to pull the rope with your hands (hey, I told you that the Japanese style of binding arm is a very restrictive method, didn’t I?), so it’s better to secure it with a loose not to a stationary object. You will tighten the construction by moving away from the object.

Escape method (we haven’t planned for any escape methods yet!) can be an ice-lock built in the pull rope between the topmost ring(s) and the SRD. A careful measuring is a must here.

Also you can use this all-in-one ice-lock:

• Connect the ice-lock rope to the karada ring (SRD at the bottom)
• Connect three rings (elbow cuffs and wrist cuff) with a simple loop, and thread the pull rope through the ice-lock SRD
• Tie the pull rope down to a stationary object
• Move away of the object to tighten the construction up

Please note that in the latter case the case the ice-lock must have a good thermoisolation (it will rest between you shoulder blades) and must be quite short.

Opinions?
