Tungsten carbide tools
Stainless steel trimming loops wear out rapidly. After turning about ten pots, you'll notice the loop becoming dull, especially with drier clay or grog. The curls come off with more difficulty, you have to push harder, and trimming becomes a frustrating task. Eventually, the stainless steel loop ends up in the trash because it's literally worn out.
Try tungsten carbide
If you don't like trimming, you're not using the right tools.
Loops made from tungsten carbide are the solution. Tungsten carbide is the second hardest material in the world. It is almost as hard as diamond. Trimming loops made from this material hardly wear down. Tungsten carbide is not a metal but a compound of tungsten and carbon. It is very sharp and only becomes a little dull after years (but you can sharpen them). Therefore, they are virtually indestructible unless you drop them or hit them hard against something. They are hard but brittle, so you must handle them with care.
Are tungsten carbide tools for you?
Most ceramists find great joy in this type of tool, but they might not be for you if:
- you're a clumsy potter who regularly drops things
- you don't throw pots but only hand build
Are you a beginner with no prior experience? You can definitely use tungsten carbide tools and fall in love with them immediately. Just know that it's an investment. Perhaps you'd prefer to wait and see if you'll continue with this hobby?
“Yesterday I trimmed for the first time with my new tools, what a joy.Thanks so much for this!"
“My favorite trimming tools. Simple, sharp, reliable. Exactly what I reach for when finishing a piece and refining the details. Good tools don’t get in the way, they support the work.”
These tools are not the cheapest but oh boy, what a difference! Trimming became so much more fun. I'm very fond of it!"

How do I use the tools?
Tungsten carbide is so sharp that you need to get used to it. Some tips:
Use leather-hard clay (slightly harder is also acceptable). Clay that is too soft will lead to “chattering,” which are small nicks in the clay that give texture to the surface. This can be beautiful, but not always desired!
Grip the tool very firmly, with your index finger on the brass or even up to the base of the turning loop itself.
Reduce wheel speed when you lose control.
Stabilize your hands. Also use the fingers of your other hand if possible to control your tool.
Work at an angle of ±45° and adjust the angle slightly if you get nicks in the clay.
Maintenance is simple
Sharpening
Only after very intensive use does the loop become slightly dull. You can easily sharpen them with a fine diamond file.

Don't drop them
Tungsten carbide is hard but brittle.
- Don't drop it
- Do not pull or twist the loop.
- Don't bang into anything hard.
- Keep them in a safe place, during and after use
Store in a dry place
The ash handles are oiled and water-resistant, but it's best to store them in a dry place to avoid warping.
I am Sofie
I've been using tungsten carbide turning tools since 2020, and believe me, I never want anything else. My first turning tool was a handmade one from Russia. Fantastic stuff. I was hooked immediately!
As a production potter, I needed high-quality tools that were razor-sharp and virtually wear-resistant. I bought from a handful of manufacturers abroad because nobody in Belgium or even Europe, made or sold them. I wanted to do something about that.
After a year of designing, seeking sustainable partners, and testing prototypes, I launched my own line of tungsten carbide tools in early 2025. Tools that I personally enjoy using, fully trust, and proudly offer to other ceramic artists.
