The Wenger Evo S10 is a retired, pocket-sized 85mm Swiss Army knife with contoured scales, a locking blade, and a basic set of tools. Unlike the the Evo 10 and its similarly-numbered predecessors, the S10 has a small blade instead of a nail file (to be consistent, it should be numbered S101). This appears to be an error by Wenger that was corrected in the EvoGrip S101 and in the Delémont series.
