The manufacture of a Cesar knife
Driven by a passion for fine guns, we gradually approached a new project ... knives. Also enjoyable as exciting, the work of these knives is a real development for the craftsmen that we are all the way to the soul. Always in search of perfection tied to the utility, we have developed lightweight Caesar knives, making them unique in their craftsmanship. We make every effort to ensure that the final product is a mixture of finesse, strength and elegance.
Metal working
The processing of the blocks
The blocks arrive as crude steel laminates, that is to say that their parallelism and verticality are not guaranteed. As a first step, we must correct them to obtain more symmetry between the two sides during manufacturing.
The block of material is then milled in order to release the future blade as well as the rounding in the guard and the pommel back - future location to attach the wood. This work is challenging - requiring many hours - is the fact that that allows us to call our knives integral, since all that is metal comes out of a single block, so there is nothing welded or pressure riveted. The term robustness finds its full meaning here.

The routing of the escape groove

This step is specific to hunting knives as it is the practice to make a groove to facilitate the flow of blood during the bleeding of game.

The cutting of the blade and the handle
The cutting is done by band saw, respecting the layout of the previously cut templates (except of course if the order is a unique knife designed by the customer). After this operation, we finish the work with a file, which allows us to gradually form the final shape to the blade.

Cutting the handle is identical to that of the blade: we follow the template with the saw and finish with a file. When we speak of the handle, this includes of course the pommel the central part and the guard. It’s therefore with a set of curves that must be followed, without troughs or bumps for the comfortable grip of the future knife.

The complete filing of the handle

The external shape of the handle is defined, we must round off all sides and remove the edges. This step is crucial to the aesthetics of the knife: the curves of the right face and those of the left face must be perfectly symmetrical.
The concave bevel and blade re file
The bevel on the blade is subject to controversy, some knife makers favor straight, in our case, we make it concave. This choice may facilitate the intrusion of the blade because the sides above the cutting edge offer less resistance than in the case of a straight bevel. This operation is roughly shaped at the wheel and ends with a file. Once the bevel is complete, the time comes to re file: this signals the beginning of the blade. The bevel line must start right along the axis near the guard.

Woodworking
The installation and of the wood filing
For most of Caesar's, the wood is embedded in the metal, which makes installing the wooden handle difficult: if the result is without hitch the operation is successful, if the contrary, the work is to be recommenced. To facilitate the operation filing, we ensure that the wood is tightly fitted in the handle.
The wood is shaped according to the filing performed on the metal previously it must follow the curves so that the join between the two is invisible.

The finish
Complete Polishing
The polishing is done with different abrasive cloths which should be "chosen" well in order to maintain the knife’s form (both on the handle and on the blade) and the rounded edges that make the general line. A second polishing - this time carried out with gum - will be required after the operations of hardening and tempering to remove the slag left by the heat treatment and to give the knife a mirror finish.

Engraving

It is the client who has ordered the knife who chooses the knife's engraving. This is done by hand - with the exception of the engraving of a logo these are machine made - by a qualified engraver. The metal is hard and during the operation, the tools must be sharpened many times so that the rendered product is to meet the demands of the knife maker.

The hardening and tempering

These two essential operations are done under vacuum in a numerically controlled oven. This limits the possible deformations of the metal and gives it a hard surface suitable for use. This is around 59 to 60 Rockwell and ensures the longevity of the cutting edge. It is at this stage of manufacture that the choice of steel plays its role. The carbon and chrome make all the difference over time to the quality of the surface by eliminating internal tensions gives a knife its longevity.


Gluing wood pads

Once the hardening and tempering processes and the second polishing is finished, it's time to glue and pierce the pads to pin them to the handle.

Sharpening
This critical phase of the work is handled by a master knife sharpener. The latter first defines the cutting edge to the backstand and gradually decreasing the grain of the bands to maximize the quality of the surface. This work is finished with leather.

Leather work
During this time, a master saddler has selected the leather requested by the future owner of the knife and made the case. Leather from elephant ears can be chosen, it is a novelty of the house but it is also a very strong and elegant material.

The knife is now finished; it will have taken from 90 to 220 hours of work - depending on the model chosen by the customer.
