This is a single replacement bit for Victorinox CyberTool Swiss Army knives: a #8 Torx driver on one end and a 4mm hex driver on the other. It slots into the CyberTool's bit holder, so it restores or extends the tool set rather than adding a new capability. It suits CyberTool owners who lost a bit or want a spare for a commonly used fastener. Buyers rate it highly, and the main thing to check is that you own a CyberTool, since the bit fits that line and not other Swiss Army models.
