The Victorinox CyberTool 29 was introduced in 2000. It adds plus scales and a Bit driver to the basic Spartan model. The bit driver and bit holder are unique to the CyberTool models (and some collectors knives like the SwissChamp XAVT).
All CyberTool models come with 4 different, double sided bits, including flat head, Pozidriv, Phillips and Torx bits. The bit holder holds 3 bits, the 4th one is stored in the bit driver itself. The bit holder/case is made of plastic which, in my opinion, looks and feels a bit cheapish. The bit driver is made from a different type of steel than the rest of the knife, judging by the color difference and the fact that a little rust is often found inside the bit driver.
