DIY Knife block

Make a knife block out of wood and acrylic

A good (hobby) cook has a suitable knife for every cutting task. Moreover, a good knife may be kept on show, so a knife block made of wood and acrylic sheet makes an attractive way to store your expensive kitchen knives. Even better, you’ll never pick up the wrong one with this knife block. A wood and acrylic knife block is also easy to make. How? You’ll find detailed instructions in this blog!


Choose the right basic materials

Because a knife block is used in a hygienic environment, it must be able to cope with getting wet and also be resistant to cleaning agents. That’s why we opt for sustainable materials: stainless steel, hardwood (of course FSC!) and cast acrylic. These materials are not readily available at the hardware store, so you’ll have to visit a builder’s merchant. For the acrylic sheet, you can go to our webshop, where we have a very wide range of acrylic. We saw every order for free, regardless of the size of your order and the plate dimensions. Moreover, you can choose from a large number of colours and shades. In our webshop, you’ll also find the spacers with which to mount the acrylic on the wood, you need two sets (eight in total). The timber merchant can help you with a nice piece of hardwood, as basic dimensions, we will keep to 25 centimetres high, 40 centimetres wide and 8 centimetres wide. At the hardware store, buy eight stainless steel screws, 4 × 30.

In our webshop, order two moulded acrylic sheets, 6 millimetres thick. As for size, you keep the height and width measurements of the wood centre block (25 * 40 centimetres). It is important that you opt for cast acrylic, the extruded version is more susceptible to cracks during drilling.

Drilling acrylic – careful measurement is the key to success

The knife block is actually a very simple construction, but your design will need careful finishing. The positioning of the drill holes in the acrylic is the key here. There is an important rule when drilling holes along the edge in an acrylic plate: the edge of the bore hole must not come close to the edge of the sheet. The minimum distance is twice the plate thickness, so in the case of a 6-millimetre plate, it’s 12 millimetres. The centre of the hole (6 millimetres) thus comes 16 millimetres from the edge on every corner. Of course, you are free to place the drill holes further away from the edge.

Acrylic sheet is supplied with a protective film on two sides. Stick wide masking tape along the edge and mark the drill holes on the tape. You drill each hole in two steps: first pre-drill with 3 millimetres, followed by the 8-millimetre drill bit. Always place a supporting plate under the acrylic into which the drill can run! With the aid of a countersink, also known as a sovereign drill, you sink the hole. This means that the head of the screw is flush with the plate surface. Countersink the hole bit by bit, and check regularly whether the screw head is already flat with the plate.

Place spacers in the wood

The coupling sleeves are aligned with the holes in the acrylic. Since the wooden block has the same dimensions as the acrylic plates, the spacers in the wood are in the same position as in the acrylic: 16 millimetres from the edge of each corner. Now the 4 spacer bushes can be screwed onto the wood with the stainless steel screws. Do this on both sides of the block:

Assemble the knife block

Place the wood block on its side and place the first acrylic plate on the spacers. Don’t forget to remove the protective foil! Top tip: treat both sides of the acrylic plate with an antistatic cleaner first. This prevents dust from attaching, and it makes the acrylic easier to clean.
Now you turn the four heads on the spacers. Don’t tighten them, as the saying goes, “fixed is fixed”, otherwise there’s a chance of the acrylic sheet tearing.
Turn the block over and place the block on the side with the acrylic plate, making sure that the block is placed on a soft surface, e.g. a towel. Now you can place the second acrylic plate. Now, there’s only one thing remaining to do: place your kitchen knives in your brand new knife block. We wish you good luck in your construction!
