Even though the current name has been officially established in 1948 and the town has a negligible Hungarian minority, most inhabitants still refer to the village as Šarfia.

Recent archeological digs found marks of habitation as early as sixth millennium BC.

The town also boasts a number of religious sculptures, dating from 1736 (John of Nepomuk), 1801 (main cemetery cross), 1801 (Saint Florian) and more.

In addition, one can find here small firms focusing on car repair, carpentry and the refurbishment of fire extinguishers.

Nearly the entire village has access to water and gas; currently almost a third of the inhabitants is also connected to the town's sewage system, which is still being under construction.

Blatné has a movie theater that operates in summer months (due to lack of heating it is closed in winter).

97.3% of inhabitants declared their nationality to be Slovak, and neither of the two largest minorities, Roma and Czech, have approached 1%.
