The idea for this design came from a commercial product that used plastic rods. Another instructabler, jliken, has posted a beautifully crafted version which you should check out ( http://www.instructables.com/id/Bamboo-Knife-Block/ ). But if quick 'n' dirty is more your style you've come to right place.
This knife block can accommodate any number of knives, depending on the size of the container you choose. It also fits odd sized knives and kitchen scissors with ease. I love the modularity and the ease of construction. For those interested in putting more effort into the appearance of the finished product, check out the last step for other construction ideas.
Step 1: Materials and tools
The oatmeal box used is about 5 inches in diameter and I needed about 12 packs (100 count) of 10 inch bamboo skewers.
For the fancier version I beefed up the strength of the box's base. I thought the cardboard base was probably too weak on its own and would deform or blow out after a while, so I used the Optional Accessories (Fig. 2) to make the base sturdier. If you don't want to reinforce the base, skip straight to step 3.
