This was a spur of the moment project that took less than 2 hours and cost less than 10$. 

Many of us have those drawers or knife blocks that dull our blades or take up space. With a new and expensive knife on the way i wanted to build a holder that would protect the blade from unnecessary damage as well as keeping it out of the way and easily accessible 


• 0.7 in. Neodymium Rare-Earth Magnet Discs (3 per Pack)
• 1/2 in. x 3 in. x 3 ft. S4S Oak Hobby Board
• wood glue
• Wood stain (optional)
• Food grade mineral oil
• sandpaper 150 grit 


• Table saw (what i used) OR router OR plainer 
• 3/4 inch drill bit and drill (if your not using a router) 

Step 1: The wooden half

the theory is simple, make the wood thin enough that a magnet can hold a knife through it.

I'll outline three different methods to do this.

Method 1 (using a table saw)

This is the way I made mine as I did not have the proper router bits 

this method is clearly illustrated in the pictures. essentially you create your own veneer 

I cut mine about 1/16th thick using the excess of the wood i bought to test the cut thickness beforehand 

Method 2 (using a router)

This is the recommend method as there will be no visible seams 

If you have a router and a dado router bit you will simply make a plunge cut in the shape of the magnet you are using at a depth 1/16th of an inch short of the total depth of the wood.

Method 3 (wood veneer)

If you have access to wood veneer you can continue to the next step 

Step 2: Safety first

** Make sure your magnet is Strong enough! **

Ensuring that the magnet can hold the knife securely through the wood will help prevent any future accidents.

Step 3: Drill holes

Find a drill bit the size of the magnet you are using (it can be slightly larger) and space them appropriately.

I spaced them 1.5 inches from the edge and 3 inches apart on center. This will leave enough room between most knifes without wasting space.

Step 4: Consider how you want to hang or mount it

I used drills and blades to carve a mounting hole for a standard wall screw however mounting plates can be bought as seprate mountable hardware. you may need to get creative depending on your mounting loction. 

Step 5: Attaching the veneer

Apply glue and clamp. you can get creative if you're like me and don't own clamps. I used 25lb weights to apply even pressure. try to clamp quickly as the veneer may want to warp once in contact with the glue.

Step 6: finishing

finishing will ensure smooth and water resistant surface finish. I started by trimming excess glue with a razer blade and sanding from 80 to 150 grit by hand. I stained and treated it with a food grade mineral oil to protect it from moisture.

The concept is simple and I encourage you to get creative with your materials.

Enjoy your new magnetic knife holder and open counter space!
