Wonderful.

As the local culture has retained a decided fashion for bronze over iron, as well as having had easy access to copper and tin for a very long time, good bronze spearheads and knives will be easy to find and relatively cheap to have made.

Aluminum bronze is a very corrosion-resistant marine bronze, too.
