Knifeboard Ekstra – extra-strong magnetic knife holder
All our magnetic knife holders and knife blocks are designed with combinations of high-quality neodymium magnets. Even so, we offer the extra-strong Knifeboard Ekstra, because we often hear from customers who want an exceptionally strong magnetic knife holder where the knives simply stay put. A magnetic knife strip in solid wood, handmade in Denmark.
The design has up to 100% more magnetic force than our standard models and is the obvious choice if you have knives that struggle to hold on magnetic knife holders from other makers. In the vast majority of cases, though, our standard models are more than sufficient and hold your knives securely and steadily.
Features:
Please note: Knifeboard Ekstra is not recommended for knives with blades in traditional Japanese high-carbon steel, which chips easily. For those knives we recommend our standard models or designs with leather, cork or linoleum, which give a gentler contact. If in doubt, feel free to ask us before ordering.
The knife holder is fully magnetic along its entire length, so you can easily hang 7–8 knives on a 40 cm model.
The magnets are invisibly encapsulated in the wood and arranged in numerous rows, so every blade has multiple contact points and a firm hold. Your knives won't slide, turn or be pulled towards each other.
Knifeboard Ekstra comes with concealed fixings and sturdy brackets; screws and wall plugs are included.
Sizes:
Knifeboard Ekstra is made in lengths from 30 to 120 cm. Height 6.5 cm; choose a depth of 2.5 cm or 4.5 cm depending on how far you want the knife holder to project from the wall. Available in solid oak, smoked oak or walnut.
Quality:
All our magnetic knife holders are made by hand in our own workshop in Denmark. Each knife holder goes through a long series of manual processes and is finally oiled with a furniture oil that brings out the natural character of the wood and gives a silky-smooth, long-lasting finish.
Custom size or a different design?
If you would like a magnetic knife holder in a custom size, or fancy one of our other designs – for example linoleum, leather or black-stained oak – feel free to contact us at info@rune-jakobsen.dk. Minor deviations from the standard sizes are made at no extra charge.
Which length should I choose?
The length determines how many knives your magnetic knife holder can hold. Lay your knives in a row with the spacing you want and measure the total width – that is the minimum length your new magnetic knife holder should have.
Which magnetic knife holders are the strongest?
A standard model 4.5 cm wide has more than enough power for the vast majority of kitchen knives. Width is therefore mainly a question of design – the magnetic strength is the same across widths within the same series.
- Magnetic knife holders 4.5–8.5 cm wide have the same magnetic strength.
- Magnetic knife holders 10–28 cm wide have approx. 50% stronger magnets.
- All Extra Strong designs have 100% stronger magnets than the standard models.
If you have very large or heavy knives, we recommend a wide or Extra Strong model. The larger magnetic contact surface keeps the knives extra stable.
Sizes in cm and inches
All sizes in the shop are given in centimetres. cm → inches: multiply by 0.39 · inches → cm: multiply by 2.54.
| cm | inches |
|---|---|
| 20 cm | 7.9″ |
| 30 cm | 11.8″ |
| 40 cm | 15.7″ |
| 50 cm | 19.7″ |
| 60 cm | 23.6″ |
| 80 cm | 31.5″ |
Knife blades: 8″ = 20.3 cm · 10″ = 25.4 cm · 12″ = 30.5 cm. For an exact conversion, a quick Google search – e.g. "20 cm in inches" – is the easiest way.

All magnetic knife holders come with two hidden keyhole fittings on the back. We use different types of fittings depending on the design, but the principle is the same.
Two screws go into the wall, and the magnetic knife holder hangs on them. Screws and wall plugs are included with your order.
If you would rather mount it without screws, you can use construction adhesive or strong double-sided tape. We usually recommend No More Nails from Pattex, but any construction adhesive will work as long as your knives are not too heavy and the wall is perfectly flat. When ordering, please leave a note in the cart so we can leave the back completely smooth and unoiled – your adhesive or tape will grip far better.
Alternatively, we can position the fittings to match two grout lines in a tiled wall. All we need is the exact distance between the two joints when you order.
Magnetic mounting
If you prefer a solution with no screws and no adhesive at all, we offer Knifeboard Magnetic — a magnetic knife holder with a magnetic back, designed to mount straight onto a fridge, extractor hood or any other magnetic surface. It goes up and comes down without tools and without leaving a mark.
If you would like magnetic mounting on one of our other designs, we can make it as a bespoke solution. Write to Kari at info@rune-jakobsen.dk and we will find the right solution for you.
(Please note that all warranties are void if the magnetic knife holder is mounted without using the mounting fittings.)

To keep both your knives and your magnetic knife holder or knife block in the best condition, always put the knives back only when they are completely clean and completely dry. Damp knives can damage the surface over time and leave marks.
Wipe your magnetic knife holder or knife block regularly with a slightly damp cloth, and avoid detergents and harsh chemicals. If needed, the surface can be refreshed with a little natural wood oil on a soft cloth.
Avoid placing the product close to strong heat sources or in direct sunlight, as this can dry out the wood and change its colour over time.
With proper care, your magnetic knife holder or knife block will keep its looks and its function for many years.

Real products, honest pictures
With us, craftsmanship, materials and aesthetics are at the heart of everything we do. Our product images are designed to give you an honest and inspiring impression of what you're getting – without unnecessary staging.
The vast majority of product photos in our webshop are therefore taken by us – whether it's a grinder, a magnetic knife holder, a serving board or one of our textiles. The images of our wooden products always show genuine, handmade products that we photograph before they are packed and sent to their new owners.
To give you a better idea of how the products will look in different homes and kitchens, we sometimes insert these original photos into AI-generated rooms or backgrounds. Only the background is artificial – the product itself is never altered or AI-generated. Every grain, edge, color, and detail you see belongs to the physical product we created.
We also occasionally receive photos from satisfied customers who give us permission to use them in the webshop. These photos provide an honest and inspiring insight into how our products look in real homes and environments.
No artificial product renderings. No misleading visual enhancements. Just real craftsmanship, photographed honestly.
Indicative images when choosing a variant
We are constantly expanding our product gallery. As many of our products come in a variety of sizes and variations, we do not yet have images of all of them. The image shown when you select a product primarily illustrates the selected wood type – 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 patterns and color play will therefore naturally vary from product to product. Please consider our images as guiding inspiration and an indication of the quality we deliver.

CREATING THE OPTIMAL MAGNETIC KNIFE HOLDER IS A MATTER OF KNOW-HOW AND AESTHETICS!
It takes knowledge and experience to choose the right type of magnet and set it invisibly into the wood, so the full magnetic force runs the whole length or width — and the blade holds just firmly enough that the knife lifts off the block or the magnetic knife holder without unnecessary force.
That is the know-how behind the magnetic knife holders from Rune-Jakobsen Design.
