The Victorinox CyberTool (CT) series was introduced almost 15 years ago. This series included 4 different models – CT29, CT34, CT41 and CT Lite. All of them has unique tool – bit driver (and additional bits). At the current moment (2015) only CT series and some SwissChamp models (XLT, XAVT, XXLT) contains this tool.
The name of model represents how many functions includes in the knife. Besides these main models, two limited editions in CT series are exists – Beretta Tool and CT 125th Anniversary limited edition.
In 2015 Victorinox renamed knives in CT series from models 29, 34, 41 to CyberTool S, CyberTool M and CyberTool L accordingly.
Why? Better to ask their marketing department 🙂
