Detailed description

Oil or water sharpening stone. Using a sharpening stone requires a lubricant, which can be oil or water (don’t mix the two).
Once the stone is lubricated with water or a drizzle of oil, you will obtain a razor sharp cutting edge by regular passes of the edge of your Morta knife blade over the sharpening stone.

Size: 16 cm long x 3.5 cm wide x 1.5 cm thick.

Atelier JHP offers stones that have two sides with 2 grains: one slightly granular for rapid sharpening, the other polished for a finer finish.

Their compact size, while still generous, makes them easy to use, both at home or when camping or hiking for instance.

Saurat natural sharpening stone

The last manufacturer of natural sharpening stones, founded in the early 1900s, is located in the Saurat valley, at the foot of the Ariège Pyrenees.

The exploitation of this schistose sandstone, with its very fine grain and mineralogical purity, which produces rational, perfect sharpening, has given rise to the creation of a full range of sharpening tools.

Any questions?

Can we visit the workshop ?

Yes. We gladly welcome you from Monday through Saturday from 2 p.m. to 6 p.m. in September to June and to 7 p.m. in July and August.
You will discover our unfiltered work environment: noise, dust and good spirits. Nothing is staged or orchestrated. One of us will give you a presentation of the material, the extraction techniques and the different product models here.

What are the differences between the steels ?

  • The stainless steel is cut in Thiers at one of our partners. It is a steel (Sandvik 14c28n) of very good quality with a remarkable cutting edge and a tried and tested cutting ability.
  • As-forged steel (the famous carbon steel 90mcv8) is hand-forged. It is an excellent steel that has a good track record. As it is a carbon filled steel, the blade will acquire a patina over time. If it is not cleaned after use on food for instance, it will rust on the surface. These blades are often intended for people who like steels that bear the marks of time and usage and require a minimum of care.
  • The Damascus blades are made from two different steels, RWL34 and PMC27. These steels are obtained by spring steel metallurgy, which after the revelation process produces random patterns for the nicest effect. This Damascus steel cuts well and the blades are stainless. No particular precaution is required.

How do i look after my Morta knife ?

With a bit of common sense and lots of love 😉
Avoid submerging your knife. For added safety, simply avoid the handle coming into contact with water, because like wood or horn, Morta is a natural material that does not like water.
You can rub a little beeswax over the handle to brighten up its colour subtleties. Place a drop of oil in the mechanism if necessary. But generally speaking, normal use requires nothing in particular in terms of care.

How do i sharpen my Morta knife ?

Ideally you should use a sharpening stone, but you can also use a whetstone or any other technique with which you are familiar. To help you, we recorded a short demonstration video on sharpening.


In all likelihood this is a Morta knife as forged. As stated above in our care instructions, the blade is not in stainless steel. It is actually a carbon steel forged by traditional methods, so the blade will acquire a patina over time. If it is not cleaned after use on food for instance, it will rust on the surface.
To remove the excess oxidization, you can clean the marks with a bit of 000 steel wool and some toothpaste. Your blade will quickly look as new again, with fresh breath too! 😉
However, after further use, the blade will once again take on a brown colour to nicest effect that will develop as you continue using your Morta.
