DIY knife block made of wood and acrylic glass

Probably the most important tool of a passionate amateur chef are his knives. So that they are always at hand and in your kitchen also wonderful come into their own, you can easily build a unique knife block made of wood and acrylic. Here's how easy it is:

The choice of the right material

We recommend using materials such as hardwood (FSC certified), cast acrylic and stainless steel. Since not all DIY stores carry these materials in their assortment, you can order them online or buy them in special metal and wood shops. Online shops like also cut your acrylic sheets for free and custom made. This saves you time and effort. Furthermore, you will also find spacers (spacers) online, with which the acrylic glass can be mounted on the wooden block.


For the knife block made of wood and acrylic glass you need the materials below. Of course, you can also decide on other dimensions, if you pay attention to the correct ratio and match the acrylic glass plates on the wooden block.

1 piece of hardwood for the wooden block:

  • Height: 25 cm
  • Length: 40 cm
  • Width: 8 cm

Metallic parts:

  • 8 spacers (2 sets of 4 spacers each)
  • 8 stainless steel screws (4 x 30 mm)


  • 2 pieces of cast acrylic 25 x 40 cm (6 mm thick), so the dimensions of the wood block accordingly


  • HSS drills (3 and 8 mm)
  • countersink

It is important not to use extruded but cast acrylic as it is less susceptible to drilling and thus reduces the risk of cracks in the acrylic.

Step 1: Drill acrylic glass

Tape the edges of the panels with a wide strip of adhesive tape and carefully draw holes on the acrylic before drilling. Leave the protective film on the acrylic glass. Although building this knife block is very easy, a good design is essential.

The positioning of the holes in the acrylic glass also plays a role: the edge of a hole must not be too close to the edge of the acrylic sheet. At a plate

of 6 mm thickness, the minimum distance should be twice the plate thickness, ie 12 mm. We recommend that the borehole should be at least 16 mm from the edge.

Place the acrylic sheet on a stable, flat surface and then drill holes in the acrylic glass in two steps. First, drill the hole with a 3mm drill and then with an 8mm drill bit. Pre-drilling ensures that the hole is centered more accurately and the acrylic plate is less stressed.

Now use the countersink and sink the hole piece by piece and check regularly that the cap of the spacer is in line with the plate surface.

Step 2: Fix spacers in the wood

The spacers should be in line with the holes in the acrylic sheets. Since the wood block has the same dimensions as the acrylic sheet, the spacers must be positioned in the same place both in the wood and in the panel, 16 mm from the edge in each corner. Now the 4 spacers can be screwed into the wood with the aid of stainless steel screws. Do this on both sides of the wood block.

Step 3: Assemble the knife block

Lay the wood block on one side and place the first acrylic sheet on the spacers. Remove the protective film on one side of the acrylic sheet and then turn the 4 caps carefully and not too tight (risk of breakage!) On the spacers.

Turn the block of wood over and place it on a towel or other soft surface so that the side with the acrylic glass plate already attached lies down. Now, based on the instructions, you can also attach the second acrylic sheet to the other side of the wood block.
