Introduction: Knife Block

Picture of Knife Block
  • This quite unusual but practical knife block is a relatively fast and simple project for your CNC machine...
  • There is some manual work involved (edge rounding, glueing and sanding) but with the right tools it won't take too much time...

Step 1: Things You'll Need:

Picture of Things You'll Need:

Bill of materials:

  • (Beech) plywood:
    • 700 x 290 x 15mm
    • 460 x 340 x 15mm
    • 350 x 340 x 15mm
    • 260 x 340 x 15mm
  • Magnet Ø25 x 5mm (NdFeB)
  • Some 6mm dowels
  • Wood glue
  • Clear varnish or walnut oil
  • 3x Felt pads
  • Your favourite kitchen knifes


  • End mill (around 3mm)
  • Corner rounding bit
  • Sandpaper


  • CNC mill
  • Manual router


  • Estlcam or another CAM Software
  • A 2D CAD Program to customize the knife slots

Step 2: Overview:

Picture of Overview:
  • Each main part consists of two respectively three 15mm boards that will later be glued together. It is much simpler to machine it this way than creating solid, thick parts...
  • Perfect alignment of the boards is ensured by some 6mm dowels...
  • The 3 main parts are held together by glued mortise / tenon joints. This is rock-solid and very simple to do on a CNC machine but you need to be aware of material thickness tolerances. If your material is considerably thicker or thinner than 15mm you should change the drawings accordingly - otherwise you'll face a lot of manual rework to fit the parts...
  • The shields knife slots need to be customized to match your blades - you can do this with most 2D CAD programs...
  • The sharpening steel is just held by a strong magnet inside the soldiers "helmet" - so it unfortunately won't work with ceramic ones...

OndrejK20 made it! (author)2017-09-21

I don't have a CNC so I had to make it manually. It's not perfect and it took several hours... but it was fun :-)

Bastian-B (author)2017-05-18

Hey, based on your idea I made my own design. A spartan like warrior knife block. Have a look here.

Thanks for sharing you idea!

pjerz (author)2017-05-17

That's a great design!

JetMechM made it! (author)2016-10-10

I made one like this. Check out the video here at

JoeyC76 (author)JetMechM2017-03-01

anyway you could email me the pattern, can't get it anywhere.

Your knife block is great. I have The Ex, it is made of plastic, I've been wanting to make a wooden version. After reading comments there are two things that you can adapt from the Ex to make yours better.

1. from people talking about the knife getting dull from contact: just like the magnet you put on the sharpener, there are magnets in the Ex on top of each knife to hold it up, and the slot is larger so that it doesn't come in contact with the sharp edge of the blade.

2. the concern about the sharp blades sticking out the back as a hazard to children or yourself: as one person suggested, leather sheaths would work, and as you can see the Ex has plastic.

I love your concept and exicution, keep it up!

ac-dc (author)nathanrudolf2016-08-25

Keep knives (and this rack) out of the reach of children young enough to not know better. Having a sheath on won't be enough, if they can still pull the knife out and play with it!

henrik von davy (author)ac-dc2017-01-23

Does this need to be said? Surely its a given to keep knives somewhere where young children can't reach them.....

RichFarwell (author)nathanrudolf2016-08-25

I know this is an old post. But, I just love your "The Ex" knife holder. Thanks for sharing that pic.

mlacerda (author)2017-01-18

Do you have, by any chance, the measures of the knives?

I'm Brazil, and I'm quite worried about the lenght and weight of the knives and if this little guy wouldn't lean forward....

maurvz800 (author)2017-01-02

Do you have a jpeg,or pdf pattern for these pieces to saw out?

Molly35 (author)2016-10-15

Lol, sorry i forgot. Who's the guy saying their could be liabilities because the knifes are exposed? Sounds like a form of PC. Its called common sense, oye!

Molly35 (author)2016-10-15

How about a version if you dont have cnc? Last time i looked i have a 8 inch joiner, 20 in planer, about $2000 worth of phiel carving chisels. More power tools then home depot.
Cnc, great tool if your doing production. Or for someone who likes to set up a program that does the work. Helloooo, a five year old could do that....

I've seen this same instructable a while ago, are the creator of that one or did you steal it?

Benne (author)xxxCHICAGOxxx2016-08-31

This Instructable was made in 2014. I think that's when you saw it first.

achmadd1 (author)2016-08-26

saya suka kreatifas anda.terima kasih.

lfoss (author)2016-08-25

I'll be 100% honest.. I didn't even read this Instructable. I just went straight to the comments section after seeing the first picture. This is the THE most EPIC knife block EVER! You need to find a manufacturer to mass produce these and start selling them retail. You could make a small fortune (or a large one)!!

Eh Lie Us! (author)lfoss2016-08-25

Somehow I don't think it's about making money at Instructables.

lfoss (author)Eh Lie Us!2016-08-26

Not generally, no. But there are some exceptions.

paolo.lattuada (author)lfoss2016-08-25

Totally agreed! I LOVE IT

ac-dc (author)2016-08-25

Haha, LOVE this design. You could sell these if you wanted to...

ortegao (author)2015-11-12

Does anyone knows the dimensions (size) of the finished product? I'm wondering how big it is, to see if it fits in my kitchen. I don't have a CNC machine nor the software to open the files. Thanks in advance!

Ghloo (author)ortegao2016-08-25

203mm tall is the figure from the piedestal to the helmet.

JAguallero (author)2016-08-25

This is so freak'n cool that even though I don't need one, I have to make it. And I feel that way about a lot of things I see on this site, but this is one that I am really going to do! I really liked the Dead Pool knife holder, but I love this. Thank you so much for sharing!!

sbkenn (author)2016-08-25

Contact your local SCA group if you want a market for them.

RodL (author)2016-08-25

It is cool looking, but I don't think anyone has looked at potentially how unsafe it could be with all the blades almost fully exposed. I am not knocking your design from an aesthetic standpoint, just trying to look at it from the safety standpoint, and the possible liabilities if someone were to build and sell this.

Hey! I'm making custom knives, and if you wanted to purchase one, just leave me a comment, and we'll figure it out! It might be hard to do cross-seas though, to Europe, etc.

I'm interested too. Please let me know how much to make it and send it to the UK? Cheers

I'm very interested in buying one of those. I live in Perú. I'll be waiting for your reply.

Impressed123 (author)2016-08-21

Would like to buy one? If anyone is happy to make one and send it to me in the UK, please let me know. Thanks

henry.sena.7 (author)2015-03-28

I'm very interested in buying one of those. Could you send me one? I live in Brazil and my wife and I loved your piece. I'll be waiting for your reply.

Hi there.I don't know if anybody respond you,in case don't, I'm planning to make one of these.It will take probably about 30 days, but if you still interested maybe I could make 2 or 3, then I'll send one to you.

Hey, I'm interested in buying one. How much would you want to make it and send it to me in the UK? Thanks

Shabraiz10 (author)2016-06-20

hi this would be a great present for my sis I'm wondering if you would selli with the knifes, I tried making it , it was a complete disaster and would be nice gift idea.

NyanRider made it! (author)2016-05-29

barlow369 (author)2016-05-13

that is soooooo awesome

xp24 made it! (author)2016-05-12

My mum found this and build it in around 15 hours without powertools. And the final product!

AndreaS117 (author)2016-04-06

Looks great. You did a good job.

T0BY (author)2015-12-08

I love the design!

apopa1105 (author)2015-10-28

I can make these for people. I have made several for friends and family. Contact me at for design options and pricing.

AprilB24 (author)apopa11052015-11-11

How much do you charge for this?

KarlyM3 (author)2015-10-28

Would anyone make this for me? I have a newly engaged fencing couple on my christmas list! If you're willing please send me the cost and I'll be forever in your debt!

kevinfelt made it! (author)2015-09-08

This was a fun little build. But I didnt anticipate how hard it would be to get the knives to sit right in their slots.
