Naturally on the bottom.
Z concrete and passion.
We create innovative Method Feeder cages. We combine the precision of 3D printing with the natural properties of reinforced concrete. For your effectiveness and the cleanliness of our waters.

What exactly is Lithos?
This is not just another ordinary sinker. It's a thoughtful tool for Method Feeder anglers, combining natural camouflage with modern engineering.
Reinforced Eco-Concrete
The main weight core made of non-absorbent, sinking material. Zero toxins in the water, perfect fit to the bottom.
No Light Reflection
The matte, porous structure doesn't scare fish — unlike smooth, shiny plastic or lead.

Feeder Anatomy
Microfibers & FDM Printing
3D Wings & Tabs
The precisely printed shell perfectly holds the bait during a strong cast and impact with the water.
Aerodynamic Shape
Designed in CAD software for maximum distance and accuracy, regardless of wind.

Why did we give up lead?
Fishing is about being close to nature, yet for years we have been poisoning it with thousands of tons of lead annually. Every broken rig is a toxic trace at the bottom of a lake that stays there for hundreds of years. We decided to change this without compromising on effectiveness.
Clean water
Our concrete has neutral pH and releases no toxic substances. It is safe for fish and the ecosystem.
New technology
We use modern 3D printing to create aerodynamically perfect forms that hold bait exceptionally well.
Locally made
The entire design and production process takes place in Poland. You support local craft innovation.
How is Lithos made?
From idea to cast on the water. A combination of engineering and traditional building materials.
CAD Design
We design in 3D software, taking care of every millimeter of the feeder. We test aerodynamics and tab placement.
3D Mold Printing
We print precise matrix molds. 3D printing allows us details impossible to achieve with standard lead casting.
Concrete Mix
We prepare a specialized concrete reinforced with microfibers. It provides resistance to water and impact against rocks.
Curing & Testing
Finished feeders cure, gaining full hardness and the characteristic matte structure that camouflages them on the bottom.
Designed
to
disappear.
Lead shines and scares cautious fish. Concrete creates a natural structure that perfectly blends with the lake or river bottom. The fish only sees your bait.
The non-absorbent concrete structure doesn't change weight during fishing.
Fiber reinforcement prevents the feeder from crumbling.
Ability to choose concrete color to match the bottom type (sand / silt).
Price of traditional lead — without the ecological "tax".
We are creating
the first
series.
The Lithos project is in the active prototype testing phase. Leave us your email and we'll let you know when we launch. You can also take part in beta testing.
