Magnets for Magnetic Knife Blocks

Super strong neodymium magnets to securely hold knives to wood for convenient kitchen storage

Neodymium rare earth magnets are the best magnets for making magnetic knife boards, knife blocks, or knife holders. They are the strongest magnets available and can safely hold kitchen knives to wood, creating an organized, space-saving way to protect and store knives.

Be sure to read our Magnetic Knife Holder strength guidelines before selecting magnets for your knife block.

Choose Wood Gap Thickness for Magnets

We recommend starting with the magnets listed in our Best Magnets for Magnetic Knife Holders article guidelines before selecting magnets for your knife block.

Strong Rare Earth Neodymium Magnets for Magnetic Knife Holders

Magnetic knife blocks built with rare earth neodymium magnets offer an effective way to maximize counter space and keep your kitchen organized. Magnetic knife boards provide secure storage for knives, cutlery, and other kitchen utensils while making them easy to access. We offer a broad selection of neodymium disc magnets and block magnets for magnetic knife blocks that are suitable for the wood thicknesses commonly used in magnetic knife holder designs.

A magnetic knife block is an excellent solution for safely storing kitchen knives while preserving sharp cutting edges. Compared to a traditional knife block, a magnetic knife holder, magnetic knife rack or magnetic knife strip offers quick access to chef knives, paring knives, bread knives, utility knives, and other ferromagnetic kitchen utensils. High-strength neodymium magnets create a secure magnetic knife storage solution that keeps kitchen knives organized and within reach, while freeing up countertop space.

Magnetic knife storage comes in two common styles: countertop knife stands and wall-mounted knife racks. Countertop designs keep knife handles facing upward, while wall-mounted designs typically hang with the handles downward. Both magnetic knife holder styles provide safe knife storage while protecting blade edges from the wear often caused by traditional slotted knife blocks. Either style of magnetic knife storage allows steel kitchen knives and other cutlery to be easily attached and removed. Be sure to space the magnets correctly and prioritize safety in your magnetic knife holder design.

Have you always wanted to build a magnetic knife holder but weren’t sure which magnets to use? Our extensive step-by-step How To Make a Magnetic Knife Holder blog article has the information you have been searching for. Learn how to choose the right magnets for your magnetic knife block, how to calculate the required magnet strength, and how to avoid common mistakes when building a magnetic knife strip. The guide also includes a detailed magnet strength chart showing holding power at different wood thicknesses, recommendations for the best magnets to use as a starting point, and answers to frequently asked questions. Whether you're building a wall-mounted magnetic knife strip or a custom wooden knife block, you'll find everything you need to choose the right knife magnets and achieve the best results.

You can use the filters in this category to show sizes and strengths of magnets recommended for each thickness of wood. If you don't see the wood thickness you are looking for, refer to our How To Make a Magnetic Knife Block article for calculation details or contact us for help finding the best magnets for your magnetic knife block.

Common Questions About Magnetic Knife Blocks

Below are some common questions and answers we get about magnetic knife racks. If you have additional questions not covered below or in our Magnetic Knife Holder article, contact us for help choosing the right magnets for your magnetic knife board.

How Do I Make a Wooden Magnetic Knife Holder?

See our comprehensive blog post, Full DIY Guide: Making a Wooden Magnetic Knife Rack, to learn how to make a custom magnetic knife block or magnetic knife rack. The instructional guide covers single and double-row magnet layouts, disc and block magnets, how to choose the best magnets for your project, common mistakes to avoid, and expert tips for achieving a strong, reliable magnetic hold.

How strong should a magnetic knife block be?

Your magnetic knife block should be strong enough to securely hold the knives, but not so strong that it is difficult to remove the knives. The stronger the magnets, the more the knife will *snap* to the wood.

Will a magnetic knife block dull knives?

No. A magnetic knife block will help keep your knife blades sharp. It is one of the best ways to store kitchen knives. There are no slots for the knife to rub against that may dull the blade over time. The magnetic knife holder keeps all your knives neatly separated, so the knives won’t rattle against each other unlike storing in a drawer.

Are magnetic knife blocks safe?

Magnetic knife blocks are safe to use when knives are placed and removed correctly and chosen magnets are strong enough. Magnetic knife blocks are inherently safer from a hygiene standpoint compared to a traditional knife block. Magnetic knife blocks don’t have interior knife slots making them easier to clean and therefore more hygienic. It’s difficult to clean the inside of a traditional knife block, allowing bacteria, dust and debris to accumulate inside.

What knives work with magnetic knife blocks?

A magnetic knife rack can hold any type of ferromagnetic kitchen knife such Chef, paring, utility, bread, steak, santoku, carving, boning knives, and even meat cleavers. Some types of knives, such as ceramic and certain types of low-grade stainless steel blends, will not stick to a magnetic knife holder.

Best Uses For Magnetic Knife Blocks

Magnetic knife blocks and racks are versatile storage solutions for more than just knives - they are perfect for hanging any kitchen tools made from magnetic steel.
