This article gives an overview of the most diverse assemblage of small polished flint tools found in settlements left by Rzucewo culture in the region of Żuławy. The presence of the tools on Rzucewo culture sites defines its range, which covers areas of the greatest abundance in amber situated near the Bay of Gdansk, the Vistula Lagoon and in Żuławy. This, apart from other evidence, proves Rzucewo culture to be different from what is widely understood as Bay Coast culture, with which it is often associated.
