Nature ClimbingKarma8a x Stone Hanger Black Edition

Karma8a x Nature Climbing: A Masterpiece of Dark Elegance

Built by two brands who live for the craft.

Only 100 pieces exist. Each one individually numbered. 

What started as an idea between Karma8a and Nature Climbing became something real: the Black Edition StoneHanger.

Born from shared design values and distinct brand worlds, the limited-edition piece brings together Danish craftsmanship and Karma8a’s visual DNA — with engraved artwork, path printing, and handwritten elements layered into every detail.

Once they’re gone, they’re gone. Don’t miss your chance to own a piece of climbing history.

What Makes the Black Oak Edition Unique?

• Rare Dark Wood: Black Oak’s deep, rich tones and natural grain patterns set this hangboard apart, creating a stylish centerpiece for your training gear.
• Granite Precision: Unlike the standard model, the Black Oak Stone Hanger exclusively features Norwegian granite, delivering the perfect texture for real-rock preparation.
• Portable Strength: Engineered to support over 100kg, it offers 20, 15, 10, and 6mm edges, enabling a full range of crimp, pinch, and edge training wherever you go.
• Skin Conditioning: Like all Stone Hangers, this version is crafted to toughen your skin and build pain tolerance for real rock climbing.

Please note: These products are made from natural materials, so variations in woodgrain, color, and tone are to be expected.

ANGLE TYPES

Our holds come in three different angles: sloped, vertical and incut. Sloped holds are the most advanced to climb on, as the 30° angle requires good finger strength and technique. Vertical holds offer a flat surface and are fairly easy to grip, which makes them very versatile in their use on the climbing wall. Incut holds have a 15° angle towards the wall,  offering a more stable grip and thus making them perfect for training on overhangs.

GRAY GRANITE / ROSE SANDSTONE

You can choose between two different stone types for your new holds / rails / hangboards. They either come in gray Finnish Granite or in the rose-colored Italian Sandstone. The granite has a naturally rough surface, which is easy to grip and will prepare your hands for outdoor bouldering in Southern Switzerland or Yosemite National Parc. The sandstone is a bit more smooth and great for training on less grippy surfaces like in Fontainebleau and the Red Rock Canyon.

RAW WOOD / SHIELDED WOOD

We offer all of our stone woodies in two different surface finishes. We can leave the wood raw, so it stays lighter in color and results in a very natural looking aesthetic and you can profit from the friction of the wood when climbing. Shielding the wood makes the wood richer in color and makes the surface water repellent and removes the friction of the wood. If you plan on washing your holds regularly, we recommend getting shielded climbing holds.

Wooden Sliders

Our sliders are designed as add-ons for our hangboards, allowing you to customize the ledge size for your training sessions by reducing its dimensions.

Each slider boasts a 6 mm (0.25") thickness and is equipped with a magnet on its back, enabling you to easily attach it to the hangboard. Additionally, you have the flexibility to stack two sliders on top of each other, effectively increasing the total thickness to 12 mm (0.5").

ENGRAVING OPTION

If you want to add a little extra personalization to your brush, we've got you covered! Add up to 25 characters and we will put our laser engraver to work. This is also a great opportunity to add contact details, like phone number, in case your favourite brush gets lost.

COLOR OPTION

To make your climb a bit more colourful, we add a color on our logo on the brushes. You get to choose which one. Can you find your favourite color?
