I'd always wondered. The blocks usually seemed designed to have the knives go in blade down, so that the blade touched wood coming in and out. But I know that when I whittle, cutting the wood wears the blade of a knife down very, very quickly. I'd always wondered if that regular contact with the wood from sliding into and out of the blocks could be wearing my knives down. Does it? If so, does putting them in blade up (against the design of the block - it would seem) do any better for them?

    Check your knives too, mine are weighted so that when inserted into the knife block, the non-blade side presses against the top of the slot. This means the blades don't touch the wood. Commented Apr 17, 2011 at 2:52

Wooden blocks are ideal for knife storage because they keep the blades dry (the wood absorbs some of the humidity in the air), preventing rusting.

The motion of inserting and withdrawing blades over wood will not noticeably dull them, because you're not actually cutting the wood or indeed even applying any pressure as you do so.

A good tip is to use a good quality steel to sharpen your knives with just one or two passes on each side before each use. Wash them with hot water by hand, avoiding dishwashers unless you like replacing your knives annually, then return them to the block once they're fully dried.

    I'd like to point out that it's a honing steel you use before each use. It hones, and does not sharpen. There is a significant difference. If you were sharpening a knife before each use it would quickly erode to nothing.

    Very good point, thanks for the clarification. I'd suggest that if you hone regularly from new then sharpening should be something you have to do very rarely.

    Just put the knifes in up side down blade up. Easy problem solved. Commented May 14, 2018 at 11:43

Technically, yes. While wood is a preferable surface to many others for drawing your blade across it will still cause wear. If you're using a block, the slots should be horizontal.

Your knife block is poorly designed. I have a Shun knife block, the blades go in sideways. I just searched for J.A. Henckels and Wusthof blocks on Amazon as well, all horizontal.

Is this worth buying a new block over? Probably not, as the other answers in this thread indicate, it's not that big of a deal. It is less than ideal however.


We have two knife blocks. One has vertical holes, the other has horizontal holes. The horizontal block gives us all the advantages of wood, without the big disadvantage you just pointed out. The cutting edges don't rest against wood all the time, and are less likely to be in contact with said wood when being placed/removed.


It's much better to put the knife in a wooden block than to put it in a drawer and have it rattle around with other metallic objects. Most pro knife sets come with a wooden block so I would assume that is the preferred storage method.

If you are concerned that pulling the knives out along the wood will dull the blade than as you pull out, also pull away from the blade side so the knife blade doesn't rub against the wood.


I'm not a whittler, but I think that what causes the blade to wear is pulling it across the wood. The blade should be fine as long as it is drawn lengthwise (like you are cutting something in half). Blades are very strong this way, but since the edge is very thin, it can easily be bent by having things pull across it.

Since wood is much softer than metal, I suspect there would be very little impact on the integrity of the blade. It it were pushed very hard into the wood, it might bend, but under normal use, I can't see any problems.


Frankly, I think the constant up and down and sliding across the maple cutting board will do much more to dull my knives than storing them in a vertical slot block.


It shouldn't matter all that much. I prefer a magnetic strip on the wall, though.


Yes, they can wear a bit in a vertical block, but only if you store them point-side down. When I had a vertical block, I stored them points-up. Assuming there's a little extra room in the slots, the tip should touch nothing when you remove the knives.


As Chris Cudmore stated, actual use of the knife on a wood cutting board will dull the blade far more. My guess would be that one average knife use dulls as much as 100's of in and outs of the block. And if you carefully pull the knife out and replace it so the edge does not even slide on the wood (as I do), then no block damage at all.


I put my sharp knives in my block (vertical) with the blade pointed inward and toward the center. I have found that when they are put in facing outward, my blades when sliding them out, have more resistance and dull more quickly.

I believe that some blocks are designed in a way that demands you insert them in a particular and that my block may be one of them. Knives are pointed towards the center because they drag on the wood when you withdraw the knives, they come into contact with the wood, which dulls them. The bottom line is that when I find my blades needing more sharpening when positioned one way over the other, the logical conclusion is that it does matter how you position the blade when in the block.
