Recessed Octagon Cabinet Knob, Solid Ash

£5.00

An octagonal cabinet knob with a recessed frame cut into the face, 44 mm across, from a single block of solid ash. Sold individually, in twelve finishes.

The block starts as a square and the four corners are cut away, then a narrow channel is routed just inside the edge so the middle of the face stands up as its own small panel. Seen straight on it reads as a frame within a frame; from the side it is still a plain, flat-fronted knob 22 mm deep. It suits doors that already have some structure to them — a shaker front, a panelled wardrobe — where a completely smooth knob looks unfinished.

Mounting
  1. Check that your door already has a mounting hole. If not, drill a 4 mm hole through the front.
  2. Pass the M4 × 30 mm screw through the hole from the back of the door.
  3. Thread the screw into the metal insert in the knob and tighten by hand, holding the four long sides parallel to the edges of the door.
  4. Finish with a quarter turn of a screwdriver — no more. Overtightening pulls the insert out of the wood.

An octagon has two obvious positions — flat sides vertical, or corners vertical — and half a turn puts it in the wrong one. Sight the long sides against the edge of the door before the screw grips. If your door is thinner than 24 mm, the screw will stand proud inside the insert; that is normal and does not affect how the knob holds.
Materials & workshop

Wood: solid ash, single block. Hardware: threaded metal insert and M4 × 30 mm screw.

Eleven of the twelve finishes use ADLER Legno Dura-Öl, an Austrian oil-based finish. It leaves a matt, open-pored surface — the colour sits in the wood rather than on top of it, so a green knob still reads as ash and not as painted board — while resisting water and household chemicals the way a varnish would. The oil is certified to EN 71-3 for the migration of heavy metals, and to DIN 53160-1 and 53160-2 for saliva and perspiration resistance. The twelfth option, Unfinished, is bare sanded ash with no coating; it is the palest of the set and darkens with handling.

Cut, shaped, sanded and finished in our own workshop in Roman, Romania. Eight outer faces and eight more around the recess mean sixteen straight lines that all have to meet at the right angle; the corners of the channel are cleaned up by hand, because a router leaves them soft. On the coloured finishes the channel holds more pigment than the flat, so the frame draws itself darker than the panel inside it.
Care

Wipe with a dry or barely damp cloth. The oil finish resists water and household cleaners, so no special product is needed and none is recommended.

The routed channel is where dust settles; a dry brush clears it faster than a cloth. Unfinished knobs have no coating and darken with handling.
