For knowledge management, just like for any other science, methods and techniques used in various knowledge processes are essential. However, despite an abundant literature dedicated to knowledge management, knowledge tools are still a poor charted area. Contributions in this area has several specialists: Kazi, in terms of systematization of knowldege tools, Samii in designing new KM tools, Meir Russ or Swartz in integrating KM tools with organizational and strategy setting. This paper presents the results of an empirical study on Romanian companies, most of them SMEs, aimed to provide an overview on knowledge tools in terms of the reasons to implement them, of the advantages and problems encountered during their use or the knowledge activities they are most suitable for. This is one of the first studies in Romania and provides some useful insights on one of the most dynamic but least represented parts of knowledge management.
