Slit pieces are cut from the 8-meter-long bar (chrome, vanadium, molybdenum). The slits are heated up to about 1,050 °C. Then it is die-forged with 3-4 hammer blows (weight approx. 2.5 tons). This creates the forging. To soften the forging piece, it is annealed at 800 °C.
The knife can now be punched out of the forging.
Now the holes for the rivets are punched out. The blade back is roughly grounded to prevent cracks.
After that the blade is embossed so it is adjusted and calibrated. At the next step, the blade is hardened.
After heating up the blades to 1,050 °C, the blades are cooled in oil. Then the oil film is removed and the blades are cooled to minus 80 °C. The structure is improved.
The blades are tempered in two stages, making them break-proof.
After adjusting, the raw material production is completed.
First, the blade is pre-grounded. The pre-grinding of the blade back follows.
The fine grinding of the blade back is now performed.
The sharpening of the bolster follows.
The inside of the handle is pre-grounded.
Pre-grinding of the bolster takes place in 5 work steps.
Fine grinding of the blade.
In the case of bread knives, the serrated edge is now applied and the wave-cut (or pointed teeth) is placed. The tomato-, cheese and steakknives get pointed teeth. Now the blade is finished and the handle can be mounted.
Crevices or small pieces of wood with square or rectangular cross-sections are cut out of the wood.
These wood pieces are contour milled.
They are adjusted to the blade handle.
Now the holes for the rivets are drilled.
To place the rivet heads, a reduction is required and drilled in the holes.
The handle and the blade are connected by rivets.
With approx. five work steps, the piece of wood is adjusted to the blade.
These five steps must be repeated with a finer sanding belt.
Now the knife back undergoes fine sanding.
The grinding of the front bolster is the next step.
Now the knife handles are pre-polished.
The middle gem rivet is now adjusted.
The handles are fine sanded and polished.
The knife edge is grounded.
The knife is sharpened and polished.
The GÜDE logo is now etched on the blade.
The knives are then cleaned.
Before the knives are ready for dispatch, each knife is inspected for quality assurance.
After quality assurance, the knives are packed in protective covering.
Now the hand-made packaging envelopes are provided with rivets and corresponding labels.
The knives are now ready for dispatch.
