Universal Knife Block (Design Martin Robitsch)

 by strooom
FeaturedContest Winner
Martin Robitsch designed this knife block, and I immediately loved it.
Because it is quite expensive, but not too hard to make one yourself, I decided to contribute another instructable.

Materials :
4 pieces of 255 mm * 140mm * 9 mm (10" * 5.5" * 3/8") in nice solid wood (I used Oak), these will be the sides of the box
1 piece of 130mm * 130mm * 8 mm (5" * 5" * 3/8"). this will be the bottom, invisible and so it can be some MDF or plywood
~2000 bamboo skewers, 25 cm long (9.8")

Other :
Wood glue
Wood Oil

Tools :
Saw : only needed if you need to cut the 5 pieces yourself
Sander : ideally a Belt sander (I use the Bosch PBS 7 AE) for rough sanding, and a Orbital Sander (I use Bosch GSS 280 AVE) for finishing
Clamps
Router (optional, I use Bosch POF 800 ACE)

Effort :  takes about half a day

Cost :  about 30$ - 25 euro. The Bamboo skewers I bought were 0.85 euro/100 pcs

Remark :
You could modify the dimensions if you want to : I just made it to the size of some Oak I had left over, and the final result is about the right size for 3 to 6 knives.

Step 1: Assembling the box

The hardest part is glueing the box together. I may seem simple, but it is difficult to glue 5 pieces together, keeping right angles everywhere. So I decided to help you with some step by step advice :

1. Put one side on a flat surface
2. Glue the bottom on top of it : Align the bottom, and one corner (in my pictures I aligned the bottom right corner)
3. Glue one extra side at the opposite corner (so I added a side to the left)

Apply clamps and some weights (I often use books)

5. Glue the remaining sides, one by one.
6. Finish by applying a bit of glue to all inner joints with your finger.

Remark :  ideally, the side will stick out just a little on all four sides. That's OK (better than being too small). This excess will be removed in the next step.

Remark 2 : It is important to take your time, take it one part at a time and let it dry enough. (my glue takes about 30 minutes, but 24h for full hardening out). So patience is your friend here !

To keep all panels exactly square, this could help

Well done !
I see you like the Wusthof knives as well :-)
Thanks for posting the pictures, I'm glad I could inspire you and I'm sure your version will futher inspire others.

wow
great idea, beautiful effect and most important its totally effective!
canable says: Jan 18, 2013. 12:29 AM
I very much like this idea. I have always been concerned about microbes, viruses, and whatever else that may make you sick. Protecting the edge is very well done with this design, and I like it! I would like to suggest plastic skewers , or quivelant, to prevent the amazing ability of germs, viruses,microbes,e-boli. whatever, staying alive in dry or non life giving areas. I am also in agreement with " mid _life_crisis " as a very good way to facilitate cleaning.

Very simple and effective.
wchoy says: Dec 30, 2012. 11:41 AM
I'm always washing my knife. So I would be more concerned that my blade of my knife would rust, if it sat on a wet sponge.

Cork sound better.
shazni says: Dec 29, 2012. 9:42 PM
OK...here is my 2 cent worth of advice...push a thick piece of Styrofoam inside the box...prick your skewers in... and you are done! the sticks wouldn't fall off and you can easily clean up. so no gluing up needed too :-)

I love this! Is there a reason you haven't entered it in the Holiday Gift Contest?
strooom (author) in reply to bajablueDec 26, 2012. 7:28 AM
Well, I was a bit too busy to notice the contest, but thanks for your suggestion : I've submitted this instructible. I made one for my parents as holiday gift and they were really happy.
bajablue in reply to strooomDec 26, 2012. 6:43 PM
Best of Luck to you!

So simple, but incredibly useful, thanks for sharing
mrsthursday says: Dec 20, 2012. 8:24 PM
A client I clean for has one of these and it's several years old and she's still happy with it- so there's an endorsement for ya.
SandLizard says: Dec 16, 2012. 8:08 PM
Brilliant. Simply brilliant!
Dr_Stupid says: Dec 14, 2012. 7:36 AM
Only problem I see, the knife's weight rests on the point, not the hilt. You'll find your points become duller and duller.
amauri12 says: Dec 14, 2012. 6:22 AM
excellent am going to build it.
Henge says: Dec 13, 2012. 9:25 AM
Do you have problems with the skewers being pulled out with the knives? How closely are they packed?
strooom (author) in reply to HengeDec 13, 2012. 10:29 AM
Normally they stay down. Once in a while, when pulling out a knife, one or two skewers slide up a few cm, then you need to push them down, which is very easy.

The tension between the skewers is easy to adjust by adding more or less skewers.
what I did was the following :
* the last `100 skewers I added in batches of 10..20 pieces (in fact that's about the amount you will get in at once, at the end)
* after adding I tested by dropping a single knife (20 cm blade) : the knife was held with the tip just above the skewers, and then dropped.
* if the tension is good (# skewers correct) then the knife falls in and stops in a smooth way with the blade completely. If the knife falls to deep you need more, if the blade doesn't slide in completely, you need less.

* with that tension, it is the right amount of skewers to put in 3 to 6 knives. Remember that also the knives take space and so increase the tension a bit.

I just realized an improvement to suggestion #2. Instead of cross drilling, carefully measure up maybe 3/8ths to 1/2 an inch from the bottom edge of two opposite sides and drive one inch brads into the inside of the side panels to create "pins" that the bottom can rest on. Glue the sides but not the bottom. When it is dry, take the bottom out and sand it just enough so it slides easily and drop it in from the top then put in the skewers. When you need to clean, just push the bottom out through the top opening.

* How do you edit a comment?
mid_life_crisis says: Dec 13, 2012. 7:42 AM
One suggestion for holding it all in place while the glue dries and another as an improvement.

1) Make a second scrap piece the same size as the bottom and position it where the top should be. Wax the edges so the glue won't stick to it. This provides support at both ends so you can wrap large rubber bands around the assembly with all four sides in position at the same time. You'll have a few minutes to work with it and get the sides straight before the glue sets up.
2. Don't glue in the bottom. Cross drill from the sides to fit in small brads that can be pulled out with needle nose pliers or tweezers so the bottom can be removed for cleaning.

to protect your knives add a few vent holes at the bottom to let any water drain away
kyshak says: Dec 9, 2012. 10:19 AM
but won't the tips of the knives get dull and chipped from the bottom?
Vodika in reply to kyshakDec 10, 2012. 7:58 PM
They should not be damaged as long as you don't ram them in as hard as you can, just use common sense.
john3347 in reply to kyshakDec 9, 2012. 1:55 PM
The soft OSB used as a base is plenty soft to not cause any damage to any knives that are long enough to touch bottom.
neetrihtneves in reply to john3347Dec 10, 2012. 11:36 AM
Ask any professional wood-butcher (carpenter!) why they use respiratory protection when working with Oriented Strand Board or any other manufactured wood product. One of the many nasty things about OSB is the formaldehyde. I believe it's part of the glue/resin mix. Hang on a second and I'll do a quick search..... Okay, here's one of the first results from a "OSB toxicity" google search http://www.healthyhouseinstitute.com/hhip_769-Oriented_Strand_board_OSB
Wilsonetics in reply to kyshakDec 9, 2012. 10:58 AM
Put a sponge or something really soft at bottom
strooom (author) in reply to kyshakDec 9, 2012. 10:43 AM
Actually the knives don't touch the bottom, only the blade goes in. As long as the box is deeper than the length of the blade of your longest knife, it is a safe way to store your knives.
XardoX in reply to strooomDec 11, 2012. 2:12 PM
i just added a flat cork piece to the bottom of the box just to be sure in the case someone is not me throw the knife on it and it goes down to the bottom, so it wont get dull or chipped :D

Thx for the Instructable ^_^
caityjay in reply to kyshakDec 9, 2012. 10:43 AM
I'm thinking you could probably fit a little silicone pad into the bottom to prevent that.
Vodika says: Dec 10, 2012. 7:50 PM
I realy like this, I have three knife blocks and they only hold certain knives made for them, but this one I can make it any size I want and hold any knife I want, this is great and it's muct safer than just throwing them in a drawer and wont damage the knifes cutting edge.
RobTurrentine says: Dec 10, 2012. 4:39 PM
It's easy to adhere to the "be nice" comment policy with this one. It's brilliant! Thanks very much.
tharper says: Dec 10, 2012. 3:30 PM
Great project! very elegant solution
Bown86 says: Dec 10, 2012. 2:33 PM
Love this!! I recently gave my knife block away because the bamboo sticks were secured to the bottom and it grossed me out that I could not clean it really well. I will be trying this as soon as I find some time! Thank you for the excellent instructable!
dlewisa says: Dec 9, 2012. 7:20 AM
Ever thought of using spaghetti or other pasta inside it? Cheap, easy to clean (you throw it in the compost), a certain foodie charm.
john3347 in reply to dlewisaDec 10, 2012. 12:45 PM
If you're gonna use spaghetti, just make a small holder using Pringles potato chip tubes. You can squeeze two or three knives into one Pringles tube that way. I already use the tubes for spaghetti storage anyway. They are a perfect size. You can decorate the tube with gift wrapping paper or wall paper to match your kitchen walls.
TheTunaMan says: Dec 10, 2012. 3:23 AM
With the addition of a small amount of weight in the bottom and some recalculation on the side. You could build this with and angle to it. This is an awesome idea!!! Thanks for the inspiration!!!
nico219 says: Dec 10, 2012. 3:15 AM
Really simple and great, Thanks.
vincent7520 says: Dec 10, 2012. 2:58 AM
Great !…
wish I thought of it myself !
Duplo for Daddies says: Dec 9, 2012. 10:31 PM
Great! I saw this design first time a few years ago, probably the original design, and I think we're getting one of them for Christmas this year. Too bad I did not see this earlier, could have saved my brother in law a few buck, since he could easily have made a nice one himself. Oh well I'll make some of them myself when I have time and give away as gifts. I live in China, so the bamboo skewers are dirt cheap! I like the idea that I can just chuck out the skewers if they get dirty, it does seem like a pain to clean out the original one if it get something in it.

Thanks!
askjerry says: Dec 9, 2012. 10:31 PM
That is brilliant!

It's simplicity is what makes it such a great design... very functional, looks great, not too expensive, and anyone with minimal woodworking skills can make one too.

You get my "Two thumbs up!" rating!
