About this Review: This review is my honest opinion of the Mercer Culinary Magnetic Knife Board Set, which I was given as a sample in September of 2022.

My take

I was excited when the Mercer Culinary Magnetic Knife Board arrived. It looked elegant and well-made. Unfortunately, several things went wrong with my copy of it, and I had to employ some creative thinking to salvage any possible use for holding my knives. It was missing hardware, the base was unrefined and didn’t stand straight, and then I scratched the base with the mounting bracket when I tried to see how it could work without the hardware.

About the knife board

  • Model: Mercer Magnetic Knife Board
  • Storage Count: Up to five knives
  • Material: Acacia wood, magnets, and stainless steel

About me

I have been traveling North America with a truck and camper for the last year. Until now, I have not prioritized proper knife storage and have allowed my blades to rattle around in a drawer that is mixed in with loose plates and silverware.

Test conditions

  • When I received it: This was given as a sample in September 2022
  • Days tested: 14
  • What I’ve used on it: Various brands and styles of knives: Santoku, traditional chef’s knife, and utility blades.

How it performs


What I was looking for

I had been waiting to make a custom drawer insert knife holder with my friend when I passed through to visit them. When this magnetic board arrived months before then, it occurred to me that I could use it for the time being or maybe just let it be good enough. Ideally, this knife board is not what I’m looking for. I need an insert that allows the blades to slide upright, so they don’t take up so much horizontal space.

Why I chose this knife board

This knife board is what I had access to, and I like to use the things I have before deciding to spend money or time on something else. However, I will most likely replace this knife board with a compact design that will give my drawer more space.

What I love about it

  • Durability: The acacia wood is very durable and will last a lifetime. The stainless steel base and mounting bracket look like they will hold up forever, but I don’t know if they will remain “stainless” as it seems like this material could rust fairly easily.
  • Flexibility: This board works pretty well with a number of blade lengths and styles, but it requires the knife's material to be made of steel, so no ceramic knives on this one.
  • Applications: This board can work well in a spacious home environment that does not have cabinets over the countertop. Otherwise, the ergonomics of reaching for a knife handle or returning the blade might be too awkward with limited clearance.
  • Size: A four to five knife storage is not impressive, but it could be enough for any minimalist. It’s enough for me, but I don’t have any extra space if I get a new knife.
  • Features: Overall, it’s a simple design with only a couple of features. The first is the wood; it’s nice to look at and is smooth to the touch. The other feature is the magnets. They easily release the knives. Yet, they have enough strength to pull the blade back into place without worrying about dropping the tool onto the countertop.

Issues I’ve encountered

  • Balance and Weight: The base of this knife board is not the right dimension or weight, and it causes the whole knife board to rock around when a blade is removed or returned. This minor instability does not inspire confidence, but maybe other people won’t mind it.
  • Performance: I was afraid to drop a knife on the countertop because of an awkward design, and then it happened. So I don’t love this design and prefer a standard knife block or even a magnetic strip mounted to the wall.
  • Ergonomics: It’s awkward pulling a knife at this angle, and it’s too easy to bump the tip of the blade on the countertop.
  • Warranty: I was unable to locate a warranty anywhere on the packaging.

Notice how the nib is not cut well and has a sharp point. I could have made this work if I filed the end enough to fit into the hole, but no one should have to do that with a new product unless the instructions said plainly that this is required

Favorite moment with this knife board

As I mentioned earlier, the board was missing hardware. When it showed up incomplete, I had to get creative so that I could still find a use for it. This made me feel clever and satisfied that the main board material still had some purpose. Thankfully, the knife board is the exact dimension needed for the drawer I placed it into.

Value for the money vs. other options

I would not recommend this knife board considering the quality of how my copy arrived. But I could see this being just fine for someone who wants this design. However, a simpler design that will have fewer balance issues is the Kotai magnetic knife holder. It’s the same price with a slightly different aesthetic but essentially performs the same job.

Final verdict

If this magnetic board had arrived complete, I would have had some better things to say about it. But ultimately, it would not have been what I needed as I could not have a standing knife block on the countertop of my camper. However, for anyone with proper space and clearance, this design could be a nice way to display the blades and give that aesthetic to the kitchen. I love the acacia wood design.
