Clay Trimming Tools – FAQ
1) Does the cutting edge last longer than typical stainless steel trimming tools used in pottery or sculpture?
Yes. Thanks to the quality of the selected tungsten carbide, the lifespan of this hard metal can be 8 to 10 times longer than that of a typical stainless steel blade.
2) Is the coating a kind of paint?
No. It is not aesthetic, but purely functional. It is a Physical Vapor Deposition (PVD) treatment. This ceramic-specific coating, applied in vacuum furnaces, adds an extra layer that improves the tool’s resistance to wear. It protects the tool against oxidation and the heat generated by abrasive materials such as ceramic clay, especially grogged bodies. We were among the first to introduce this technology into the field of ceramics.
3) Does tungsten carbide have any drawbacks compared to traditional materials used in pottery or sculpture tools, such as steel?
Not in normal use. Tungsten carbide is superior in most performance indicators when trimming or shaping ceramic pieces. If there is one drawback, it is that if the tool falls to the floor and receives a strong impact, the cutting edge could chip or break. Although much harder than steel, carbide is not flexible.
4) What types of clay are carbide tools recommended for?
Carbide tools perform especially well with abrasive clays, grogged bodies, and hard clay bodies, where steel tools tend to wear out quickly. They can also be used on fine clays, but they really stand out when the clay is particularly aggressive on the cutting edge.
5) Do carbide tools need to be resharpened?
No. One of the main advantages of carbide is that it does not require frequent resharpening. With normal use, the tool can last for many years without any noticeable loss of performance.
6) Are they suitable for beginners, or only for advanced ceramicists?
Yes, they are perfectly suitable for beginners. In fact, many beginners appreciate that the cutting edge remains consistent over time, making the trimming process more predictable and controlled.
7) How should I take care of a carbide tool?
-Avoid dropping it on the floor
-Do not use it as a lever (it may break)
-Store it separately from other tools to prevent impacts
