We propose a definition of improved Milnor K-groups of local rings with finite
residue fields such that the improved Milnor K-sheaf in the Zariski topology is
a universal extension of the naive Milnor K-sheaf with a certain transfer map
for etale extensions of local rings. The main theorem states that the improved
Milnor K-ring is generated by elements of degree one.
