Creating a chest structure with diamond shapes is such a classic that you can find rope with pre-tied knots in some Japanese sex shop to create this tie. It is often referred to using the Japanese names karada 体 (body) or hishi 菱 (diamond). A similar tie is named kikkoo 亀甲 (turtle shell) for a variation with hexagons.

This type of harnesses is often used as a decorative tie, but you can attach other limbs to the structure for something more restrictive. The diamond shape can be more comfortable when we pull on it than the ladder structure because of how is distributes the pressure.

Opening diamonds

The most common way to tie diamonds on the chest is to place the bight behind the neck and make knots in the front. Then you can continue toward the back by going between the legs. After you catch the bight behind neck, you can come back to the front and open the ropes between the knots into diamonds.

Opening the diamonds will make the tie progressively tighter, watch out for the ability to breathe of the person being tied. Make sure you discuss ahead placement between the legs. You can split ropes after one of the knot to go around the waist instead.

Drawing Diamonds

You can also create a structure with a diamond pattern using half hitches and crossing hitches. The aesthetic will be similar to the Karada, but the difference in construction bring makes the placement of the rope more precise and the tension in the tie more constant throughout the process of tying.

If you make a spiral and then make a second spiral in the opposite direction on top of it, diamond shapes will emerge.

You can progressively add diamond shapes by making consecutive x shapes.

Practice Time!

Make your own diamond harness!

Self evaluation checklist:

  • Frictions are compacted and tight with no undesired twist
  • Ropes are flat against the body, no uncomfortable twists
  • Tension is even across the tie
  • Is the tie symmetric?
  • Pull on the tie in different direction to measure it’s solidity

Exploration ideas:

  • Different sizes/numbers of diamonds
  • Different level of tightness
  • Tie only on the upper chest, or expand to include the entire upper body?
  • Single ropes or double ropes
  • Try to use the diamond to frame or enhance something you like
  • Reverse the tie to focus on the diamond on the back like a tortoise shell
  • Create a harness with diamonds on both sides (front of chest and back)
  • Create the diamond pattern without using any knots
