Japanese style arm-binder. Self-bondage ideas.

Japanese style arm-binder -01This 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:

  • your 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.

  1. But I do need some advices on the time-release. For example, you can’t freeze the mentioned ice-lock in a hotel. I tried.

  2. This looks very intersting and I am begining to see the possibilities of use for SB, but need to work on it a little longer.

    Hotels can be a nightmare for ice release options – you might be lucky and have a free ice vending machine (about 40% of the hotels I use have them) or you caould always order a drink with ice (at hotel prices!).
    Ra is correct that most hotel rooms only have a fridge for cooling drinks, not freezing water – once againI ask the question, should we self-bondage fans start to demand such facilities in all hotels? 🙂


  3. Yikes…
    First thing that came to mind when seeing that (rather nice) contraption, was the Manga drawing of that girl in a blue leotard with that SB-gone-wrong scenario..
    It’s basically the same. The lower arms in a shared cuff and locked in place with restraints around the upper arms. Looking at the picture, you can see that all is centered around a single o-ring on the back. Replace that with the release mechanism, something that can be put in place easily enough in the first place and bingo.

    Whatever the hack that would be? Good question… :\

  4. I tried a light version last night using only the wrist cuffs. I made them just as wide to be able to wiggle my hands in, not using any elbow cuffs. I found it relatively easy to get the hands in but nearly impossible to get them out again. Problem is, when you are pulling the hands apart, the cuffs are being pulled against the wrists and thus tend to lock themselves. I absolutely agree, with elbow cuffs its inescapable. Now how to release these?

    Best wishes


  5. I think I know what the front MAY look like. The lower strap needs to go under the breasts. A second strap connects to the lower strap and could go between the breasts to a steel ring just above the breasts. Then the 2 sholder straps would be connected to the ring just above the breasts. Adjustments could be done by adding buckles to the front.

    Just a thought
