On a folding knife, it is the end of the spring, towards the blade. Originally flat and raw, the cutlers then carved floral decorations, animal or emblematic decorations.
Laguiole knives most often present a bee decoration.
The bolster is the part between the blade and the handle.
GOYON-CHAZEAU bolsters are forged bolsters ; Blade, bolster and tang are shaped in the same piece of steel.
The bolster bring a notion of weight and balance to the cutlery piece.
Other types of bolsters exist on the market : molded, inserted, welded, hollow bolsters…
Decoration made ton the spring edge.
GOYON-CHAZEAU proposes 2 kinds of chiselling : machine chiselling and handmade chiselling.
Sharp part of the blade, intended to cut.
Cutlery heads, cutlery tops
They are the blades foe knives, prongs for forks, bowls for spoons.
Cutlery pieces, complementary pieces
These are all the pieces that can be added to the dinner set (dessert knife, fork and spoon, fish set, ladle, cake server, salad serving set…).
Damascus, damas steel, damask
Damascus is a material resulting from the mixing of differents steel lays. This, forms a mixture that make each piece unique.
Damas steels are stronger, harder and more edged.
Nowadays, damas steel is produced in two different ways, both proposed by GOYON-CHAZEAU :
The industrial damas (or damas stainless steel) comes from powder metallurgy. Damascus drawings are technically mastered.
The handmade damascus is made by a blacksmith who will weld several shades of metals with each other. Hammered, turned, folded or stretched multiple times, the mixture will gradually draw shapes in the mass.
The handmade damascus used by GOYON-CHAZEAU is made by the blacksmith Alain DUMOUSSET.
GOYON-CHAZEAU handmade damascus knives have an added cutting edge made with carbon steel.
It is the final appearance of the stainless steel.
GOYON-CHAZEAU proposes :
- Brilliant (or mirror) finish: steel is polished to perfection and reflects as a mirror;
- Matt or brushed finish: steel has many surface streaks to give a matt aspect;
- Sandblasted finish : steel presents a granular surfaced which also give a matt aspect.
Small piece of steel placed horizontally in the hollow of the handle of a folding knife. It stops the blade when it closes before it touches the spring.
Locking mechanism for closing knife blades by which the spring, which has a bulge, is wedged in a notch on the heel of the blade.
Both hands are needed to disengage the system by pressing both the blade and the handle.
To grind, grinding
Action of raising metal on the blade to make the cutting edge.
There are several types of emouture. GOYON-CHAZEAU proposes a V grinding, or full blade cutting edge which allows the widest use. It offers a strong and efficient cutting edge and is suitable for both right-handed and left-handed users.
Handle side, cover
Material pad(wood, acrylic, horn ...) which is fixed on the tang or the liners and form the handle.
Hardening, hardened blade
Hardening, oftenly signify all the quenching, that is to say the heat treatment (hardening + tempering), done on the blade.
Hardening consists in suddenly cooling a blade brought to high temperature by immersion in water or in a specific oil. This improves the quality of the steel and increases the hardness.
It is supplemented by "tempering", which consists of heating the tempered steel and cooling it slowly to make it more malleable and resistant to shocks and deformations.
Steel hardness obtained after heat treatment and which is measured, in cutlery field, in Rockwell HRC.
Below 52HRC, steel is too soft to give sharp to the knife.
Above 60HRC, steel becomes more fragile and brittle and make the sharpening very difficult to maintain.
Plates, mostly in stainless steel, which sometimes serve as support for handle sides and/or welded bolsters.
They are placed on the tang, provide rigidity and strength to the handle and protect the fragile materials that can not be fixed directly on the tang. They finally add weight to the knife and make it more qualitative.
Ornament made by planting small nails on the handle.
Demarcation line at the end of the cutting edge just before the handle. It is formed during the grinding and shows the thickness that has been removed from the blade to make the cutting edge.
Knife that does not have a bolster.
To sharpen, sharpening
Action performed on the cutting edge to give it a suitable thickness for cutting
Mechanical part that allows opening and closing of blades on certain folding knives.
GOYON-CHAZEAU proposes 3 kinds of the springs : Plain forged spring, forged spring with machine chiselling or forged spring with forged bee and handmade chiselling.
Riveting is one assembling and fixing principle to place and maintain the handle on the tang. The rivet, a metal cylinder, is placed in force to hold the parts together.
Extension of the blade in the handle to fix it.
Several types of tangs exist: Narrowing tang, partial tang, half tang…, which only occupy a part of the handle, and the full tang which occupies all the handle.
A full tang is a guarantee of quality, strength and balance.
