Question: I see that there are bolts on the side of the block.  Do they hold it together? Can you remove an inner portion for a narrower block?
Document: This product was 90% when I got it. The construction is good and the size is perfect. The only issue was the block was loose. There are two long bolts that keeps everything together. A quick tightening with a wrench and it's now 100%. I'm very happy the purchase and would consider it again!
Bought this to store new knives. Great because the 6 segments are held together with threaded bolts/nuts so the width can be changed to fit different drawer widths. In my case, I removed one section to fit into my drawer. NOTE: You'll have to cut the threaded rods down after removing a section.
This knife storage In-drawer block was great. It fit perfectly. My knives are no longer jumbled together in the drawer. I am very happy with the block.
Absolutely love this product! I needed an in-drawer knife block to hold a lot of knives, but I was short on space. When I found this product, I was very excited. It turned out to be exactly the right size, and it's so easy to access my knives. I definitely recommend this to anyone with a narrow drawer but lots of knives to store.
I think this is a standard design to have the slats but no bottom, however, since these are to hold knives it would be better to have a bottom so that the knives to not mark the bottom of the drawer in any way. Also, the tips of the knives can hit the back of the drawer also causing marks in the drawer. Other than that, it is great to have a knife block made of a sustainable material, bamboo, that also provides water resistance and therefore warping protection.
This block is good quality exactly as I expected, would buy it again. Solid, holds many knives and steak knives too.
Fits perfectly next to a similar knife block I already had in my knife drawer. Seems to be well made, very functional.
Exactly what I expected and wanted. Keeps my knives organized and easily available. What more could I want from a knife block?
I was cutting my fingers when I reached into the kitchen drawer for a knife. This storage block safely and securely holds 5 large knives and 6 smaller knives.
I consider this a low profile knife storage block. I put a rolled up towel at the back of the drawer to keep the storage block from shifting to the rear. Recommend this storage block.
Answer: Just looked: there are small hexagonal nuts on each side (not bolts), and they are inset so that you'd need a tiny socket head to turn them. I'd say they're screwed onto a long pin with a little thread at each end. However, it is possible that the thread goes the whole length of the pin, in which case you'd need to saw a length off in order to make the unit more narrow.Oh, and the nuts are around 5/16 " diameter.
