'Blackboard X-tra' - extra strong black stained knife rail from 40 - 80 cm in 3 widths
Including VAT. Shipping calculated at checkout
All our knife holders are handmade to order.
If you order today, your knife rail will be ready for shipment during week 45 (November 3 - November 9).
We often receive requests for strong knife racks in an even darker shade than smoked oak, so we now offer selected designs in solid, black-stained oak – for those who want a deep-black magnetic rail with exceptional holding power.
Blackboard X-tra is magnetic along its entire length, allowing you to hang 7–8 knives on a 40 cm model with ease.
This version is primarily recommended for knives made of Damascus steel or other alloys that normally struggle to adhere to standard magnetic rails. For most knives, however, our standard rails will deliver a perfect result.
We do not recommend the X-tra rails for knives with blades made from traditional Japanese high-carbon steels such as Aogami or Shirogami. For these, we suggest one of our standard rails or a version with a leather or linoleum surfaceinstead.
Blackboard X-tra is available in standard lengths from 40 to 80 cm and offers 100 % more magnetic force than our standard rails.
Inside each rail are several rows of powerful N52 neodymium magnets running the full length, ensuring maximum adhesion regardless of the size or weight of your knives. You won’t find cheap disc magnets drilled in from the back here – a shortcut often seen in other products.
We use bar magnets that are invisibly embedded in the wood and arranged in multiple rows to give each knife blade optimal contact at several points. This prevents the knives from slipping, rotating, or attracting each other.
Finish
Unlike industrially spray-lacquered products, our black knife holders are hand-stained with a brush – a time-consuming process that gives the surface a vibrant and authentic character. The subtle traces of brushstrokes are a hallmark of true craftsmanship, making each knife holder unique.
All Blackboards come with concealed mounting; all necessary fittings, screws, and wall plugs are, of course, included.
A Conscious Alternative to Mass Production
In a market dominated by mass-produced knife racks and blocks, we have consciously chosen a different path.
Each knife holder is made to order in our small, specialized woodworking studio – crafted with care, respect for the materials, and in close dialogue with you as the customer.
This means you'll only find exclusive, handcrafted knife holders here – designed with equal focus on function and aesthetics.
Handmade in Denmark – Delivered Worldwide
Our knife holders are considered among the strongest and most refined on the market.
For nearly 10 years, we’ve been crafting and delivering custom-made knife racks and blocks to private customers across the globe. Every piece is made to order in our small workshop, beautifully located in the northernmost part of Denmark.
Here, Kari and I work with care, precision, and dedication – always keeping your specific needs and preferences at the center of the process.
Fully Magnetic Design – Flexible Placement, Strong Hold
Place Your Knives Freely – Without Compromise
Unlike traditional solutions, our knife holders are fully magnetic. This allows you to position your knives anywhere on the surface – with no limitations and no risk of sliding or clumping together.
Powerful, Premium-Grade Magnets
We use only high-quality Neodymium magnets – custom made and imported directly from our trusted manufacturer.
While many knife holder brands rely on spot magnets or cheap disc magnets, we embed several uninterrupted rows of strong magnets inside the wood – strategically placed to ensure that each knife makes multiple contact points along the blade.
How Much Weight Can They Hold?
We’re often asked how many kilos our knife holders can support. The truth is, it depends on how it's measured and slight variations between models and designs.
However, all of our knife racks are guaranteed to have sufficient magnetic strength to securely hold the vast majority of kitchen knives available today.
It’s no coincidence that our knife holders are regarded as some of the strongest and most precisely made on the market.
Extra Strength for Special Needs
In the rare case where a knife doesn’t adhere well to a standard rack – for example, very heavy knives or blades with low magnetic content – we offer the X-tra Strong Series. This version delivers approximately twice the magnetic force of our standard models.
Craftsmanship and Aesthetics in Every Detail
We view our knife holders as functional pieces of furniture – and that mindset is reflected in every step of the process.
Every detail matters: from the carefully selected FSC-certified oak or walnut to the meticulous construction and final hand-sanding that creates a smooth, elegant surface designed to age gracefully.
Each piece is finished with an eco-friendly furniture oil and discreetly stamped with our signature – Rune-Jakobsen – as a mark of quality and responsible craftsmanship.
Tailored to You – Standard and Custom Designs
Our webshop features a range of standard designs in fixed sizes – including wall-mounted knife racks and freestanding blocks. But we also offer fully customized solutions made to your measurements and preferences.
Minor adjustments to dimensions or mounting hardware are included at no extra charge. We’re also happy to offer non-binding advice if you have special requests regarding mounting, materials, or design.
Flexible Mounting Options
All knife racks come with hidden mounting brackets and the necessary installation kit. If you prefer not to use screws – for example, on a tiled wall – we can supply the rack without mounting hardware so it can be installed using adhesive such as "No More Nails." Just leave a note at checkout with your request.
100% Satisfaction or Your Money Back
We understand that ordering a handmade product online without seeing it in person can feel uncertain. That’s why we offer a full return policy – even on custom-made items. If the final result doesn’t meet your expectations, we’ll take it back – no questions asked.
The Small Difference That Makes a Big Impact
We don’t create disposable products – we create lasting, beautiful pieces with soul and character. Our goal is to provide you with a knife holder that not only serves its function but enhances your kitchen aesthetically – for many years to come.
Browse our collection online – or get in touch directly if you’re looking for something truly unique.
Which length should I choose?
The length determines how many knives your rail can hold. A good rule of thumb is to line up your knives with the desired spacing. Then measure the total length – and you will have the minimum length of your new knife rail.
Which width is best?
The width is primarily a question of design, as the magnetic force is the same across all widths within the same series. However, if you have very large and heavy knives, we recommend a wider model. This provides a larger magnetic surface and ensures that your knives are even better secured.

All measurements in our webshop are given in centimeters (cm).
If you use inches (inches), you can easily convert with these formulas:
* 1 cm = 0.39 inch**
* 1 inch = 2.54 cm**
**Examples of conversion from cm to inches:**
* 20 cm ≈ 7.87 inch
* 40 cm ≈ 15.75 inch
* 60 cm ≈ 23.62 inch
* 80 cm ≈ 31.50 inch
**Examples of conversion from inches to cm:**
* 10 inch = 25.4 cm
* 20 inch = 50.8 cm
* 30 inch = 76.2 cm
We recommend using an online converter for accurate conversion.
All knife rails come with two hidden keyhole brackets on the back.
We use different types of keyhole fittings depending on the design, but the principle is the same.
2 screws are drilled into the wall to which the rail is attached. Screws + raw plugs are included when ordering.
If you want to mount without screws, you can use a mounting adhesive or strong double-sided tape. We usually recommend 'No More Nails' from Pattex, but any mounting adhesive will work as long as your nails are not too heavy and the wall is 100% flat.
Alternatively, we can place the keyhole brackets at a distance that matches two joints in a tiled wall. This simply requires that we be informed of the exact distance between two joints when ordering.
When ordering, please leave a note in the shopping cart so that I will make the back completely smooth without oil treatment so that the tape/adhesive sticks better.
(Please note that all warranties will be void if the knife rail is mounted without the use of mounting brackets.)
You can now get all RJ Woodworks products with copper details as an alternative to brass or aluminium for an additional charge depending on size and design.
If you are interested in inquiring about the price for a product with copper details, please feel free to send an mail
We only use carefully curated FSC certified furniture wood. The primary woods are oak, smoked oak and walnut. In addition, we offer a number of special types of wood that are sold in conjunction with special orders, e.g. Teak, ash, chestnut, golden rain, cherry, wengé, zebrano, beech, etc.
We finish all products with a high-quality wood oil, but if you would prefer e.g. an oil with a white pigment, we can of course do that too - the desired final treatment can be mentioned under the remarks of the ordering.
If you do not find what you are looking for on this page, or if you have questions, we can be contacted by phone +45 4243 4393 or mail.
NOTE that we are always trying to create unique and elaborate products with an exciting visual expression and colour profile. You should therefore take our product photos with a grain of salt and not as a guarantee of how the finished product looks.
Remember, wood is a living material. There are no two pieces of wood that are identical, so all product photos are only indicative.
You can do a little surfing on our website and see examples of products we have made in the different woods to get a better impression of the colour variations of the woods, structure and expression.
If you are in any doubt about choosing a type of wood for a product, you are welcome to contact us for a chat about the possibilities. We gladly counsel and seek to inspire 😊
Real Products, Honest Pictures
For us, craftsmanship, materials and aesthetics are the focus. Our product images should give you an honest and inspiring impression of what you get – without unnecessary staging.
The vast majority of product photos in our webshop are therefore taken by ourselves – whether it is a grinder, a knife holder, a serving board or one of our exclusive textiles.
The images of our wooden products always show real products that we have handmade for a customer and photographed before they were delivered.
We also occasionally receive photos from satisfied customers who kindly allow us to use them in the webshop. These photos provide an honest and inspiring insight into how our products look in real homes and environments.
A Guide to Variants
We are constantly expanding our product gallery. As many of our products come in a multitude of sizes and variations, we do not yet have photos of every single one. The image displayed when you make your selection primarily illustrates the chosen type of wood – not necessarily the specific size or design variation.
Every Piece of Wood is Unique
Wood is a living, natural material, and our passion is to create unique products with character. The grain and play of colours will therefore naturally vary from one product to the next. Please consider our photos as a source of inspiration and an indication of the high quality we deliver.
Any questions? We're happy to help.
Do you have questions about a design, size, type of wood, or do you have special requests? Please don't hesitate to contact us at info@rune-jakobsen.dk, and we will guide you to the right choice before you order.

Notice Regarding Temporary Suspension of Shipping to the U.S.

This situation is untenable for both you as a U.S. customer and for us as a European company, so we have decided to temporarily suspend shipments to the United States.
We sincerely apologize for any inconvenience this may cause our U.S. customers. Sales will resume once these restrictions are lifted or adjusted to a level we consider fair for our customers and sustainable for our business operations.
