The SwissTool was revolutionary in the multitool industry because it solved many of the problems associated with multitools- the implements are accessible from the outside so you don’t have to open the pliers, the implements lock and the handles are comfortable- there’s no bare sheet metal edges like on some other early tools.

All in all, the SwissTool is one of the most popular multitools around, and has a very well deserved reputation for corrosion resistance, toughness and all around utility.
