We present the results of the analysis of about 300 short gamma-ray bursts (GRBs) detected by Konus-Wind (KW). The sample is one of the largest detected with a single instrument. We present the classification of the KW GRBs. For the short GRBs we provide the results of the localization by triangulation and the spectral analysis. Using the localization information we discuss the possibility of association of some short GRBs with the extragalactic magnetar gain flares and obtain an upper limit on the rate of such events. We show that most of short GRB spectra are well described by a power law with exponential cutoff with the peak energy of EF(E) spectrum up to 3 MeV. We found an additional power law component in three short GRBs. We present a detailed analysis of short GRBs with extended emission. Finally, we consider the results obtained in the context of the Type I (merger-origin) / Type II (collapsar origin) classifications.
