We left Opinel in the XVIII century. One a goldsmith
at Dole, the other an iron merchant cited in the members list of the Société
Populaire de Saint-Jean-de-Maurienne in 1792. Is this the father of Victor-Amédée
Opinel, born in 1799? |

In June 1980, the Swiss artist Christian Sigrist rebuilt a tenth of the size of Daniel's workshop, such as it was a century earlier. Simple but a robust building made out of wood on a foundation of stone and incorporating a square room in which could be found a sort of shed with a sloping roof. The river Arvan was the very heart of the establishment, the force which drove the hammer, stirring up the embers of the forge and making the grindstones turn. At the back of the main room, the feeder canal can be seen, a wide wooden duct with its vanes on a paddle wheels. In the left-hand corner, a water pump. |

On the model can be seen a simple vertical tube, pierced with holes. On the inside, the water arrived under atmospheric pressure which then passed through a neck making the water travel faster with very powerful induction. This clever machine sucked up the air which was then directed to the hearth of the forge. An essential part of the unit, this forge occupied the left-hand section of the workshop, on the other side of the wall to the shed or main workshop. It can be clearly seen on the model with the coal, the shovels, pokers, hammers, pliers and pincers. |
|   Next to the forge - in the foreground
of the model - the assembly table, with files and chisels. On the vice the
artist has included a billhook blade, here called a "goyarde", a formidable
tool with the tip bent forwards. Mauriennais country folk skilfully made
use of it in order to prune, clear undergrowth, cut wood or to sharpen a
stake. A tool that was often used daily, but not as often as the knife,
which was often hung from the belt with hooks fixed to the handle. The centre of the room is occupied by the anvil, which is being used by the blacksmith to forge axes. The right-hand side of the workshop is the "mechanical" part: a paddle wheel drives four "artifices (devices)". In the background is a sandstone wheel on which a worker is sharpening a billhook. A simple but clever technique in which the grinder was seated on a board where he could press the blade exerting a minimum of effort. Then there are the two hammers. On the model, a blacksmith is standing up in front of one of them, while a man sitting on a seat suspended from the ceiling is using the other. This layout enabled the blacksmith to swing the hammer around in order to always have the part in the best possible position. The two assembled sprocket wheels can be clearly distinguished, as well as the flywheel, on the drive shaft. These are the sprockets which rhythmically work the hammers. In Daniel Opinel's workshop, the varying distance of the sprockets enabled a specific rhythm to be attained for each hammer, corresponding to the different tasks that were to be carried out. The speed of the wheel could be adjusted of course : all that was needed to be done was to open the water arrival vane by a special lever. Finally, in the foreground and worked by a crankshaft, there are shears enabling the blacksmith to cut the steel bars. |

  Placed against the main building, this
adjoining room was the area reserved for the grinders. Worked by a paddle
wheel, two very large grindstones bathing in the water of the outlet duct
: the stone had to be always wet so as not to overheat the blades, which
could harm the hardening process. The grinder worked lying on the bench,
holding out the blade which was to be worked upon. In order to achieve maximum
force, the worker could adjust the height and angle of his bench. He could
thus compensate the wear on the grinding surface. This was changed when
its diameter became too narrow. |
||
| At the start, it was between 1.50 m
and 1.80 m but two or three years later it was reduced by two thirds. Traditionally,
the grinder chose his own grinding wheels which he carefully prepared himself
and then put in place. He would not give the task to anyone else to do because
the quality of the stone and its assembly had his life depending on it.
Indeed, the consequences of this heavy solid mass fracturing when turning
at 25 revolutions a minute would have dire results for the person positioned
30 centimetres above it! |

| In the model made by Christian Sigrist, a dog can be seen lying on the legs of the grinder. Indeed, it was traditional that the grinder, motionless on the bench and labouring in a humid environment due to the spray from the grinding stone, had a four-legged friend in order to keep the bottom part of his body warm as well as, perhaps, simply keeping him company. |
