DIY Wrist Device

[straitlaced8b]

I have put together a DIY (self-)bondage device that is cheap, easy to construct, durable, and secure.

Supplies:
- 1" polypropylene webbing (very cheap, can be found at sewing stores)
- Adjustable "parachute" buckle (x1 or 2; about $3 at sewing stores)
- Hand-sewing supplies (to form the belt)
- Hot glue (optional; to prevent fraying)

Buckle #1, the key to the restraint, is used in a nontraditional way. Pass the polypropylene belt through the inner of the two holes on each half of the buckle (see photograph). Form it into a loop of the perfect length so that once the buckle is closed, the wrists are cinched together and cannot be pulled free. This may take one or two tries. Once you find that perfect length, sew the loop closed; I hand-sewed the overlapping area with doubled thread using a whipstitch around the edges and a few sloppy stitches elsewhere, about twenty in total, creating a surprisingly strong loop. You may want to seal the cut edges so they don't fray.

The optional buckle #2, for the adjustable waist belt, is "threaded" according to the usual instructions. To link the waist belt to the wrist strap, use the unused outer hole of the wrist buckle.

To use the wrist device on your own, ensure that the buckles are lined up, and the corner of a rounded table to push them together. (Safety tip: just as with handcuffs, if the thumb side of your wrist is up against a hard surface for a long time, you can pinch a nerve. So don't turn your wrists sideways into the buckle and then leave them there for hours.)

To release the buckle, both sides of the buckle need to be depressed simultaneously, so getting out on your own is a little harder. With the proper household items, and with the wrists in front, you can do it in a few seconds. Without any items, or with wrists behind, it's near impossible. But isn't that what a restraint is all about?

So, the loop can't be adjust  according to the diameter of the wrist ?  I mean, if I want to play with someone else 😊

A good idea but one warning, I had one of those 'parachute buckles ' fail while hiking. Suddenly my backpack was hanging off one shoulder and when I checked the broken buckle it was almost hollow inside due to a fault in the casting process. I know it was probably a one-off event but it's put me off trusting them with any serious stress. 

Also, rather than use hot glue to stop the webbing fraying you could just singe the cut ends with a match.

It's a good idea.
I think it's clever.

Without any items, or with wrists behind, it's near impossible.

How to get out, then? 😉

Tap the buckle on a table edge.
As you put tenchion on the buckle, just tap one side then the other, and it will pop open. It does take a bit of skill, but for me, it's easy.

As Tinker D mentioned, it is possible to open such buckles one tab at a time, provided that you keep continuous tension on the opened side (similar to how one picks a lock, tumbler by tumbler). But it does take some skill, especially when your wrists are bound, because if you ease off, the opened tab snaps back into place. I wouldn't call the process "tapping," like one can do with cheap handcuffs. Those tabs are pretty tight, so it requires deliberate pressing.

Because the tabs end up shielded between your wrists and between your forearms, pressing the tabs with a table directly is rather difficult. My solution for hands in front is to press the tabs simultaneously: the lower/forearm tab using a certain object placed on the table, and the upper/wrist tab using a pencil that has an eraser (using the eraser, for grip, on the tab).

Vixien, the wrist loop cannot be adjusted. But because the webbing does not have any give, one size of wrist loop can restrain a range of wrist diameters. The same loop works for me and my girlfriend.

If you like physics and draw a force diagram at the buckle, you will find that the buckle is actually subjected much less tension than is placed on the loop (which, as I mentioned, holds very well without much sewing). It's for this reason that cinches are so effective.

This is a great idea! I have made many kinky things with webbing and buckles and didn't think of this one. Time to pull those supplies out and play around.

Thanks!

A cunning tip to prevent the webbing freying is to cut it with a hot knife.
Just heat an old knife over a flame and then cut as you would normally, make sure it really hot and don't pull the two parts apart too much, just gentle tension. The ends will have a clean and sealed finish to them.

I experimented with this tonight and I found that my wrists are too small for it to work.

To get my wrists into the loop, the the loop must have a tiny amount of slack. That slack is still there when I buckle the device together!

This technique relies on the buckle cinching the webbing between your wrists when buckled.
My buckles are just over 2" in length from strap to strap. My wrists, unfortunately, are about the same size in width.

It was a fun exercise but now I have to figure out something else to do tonight.
