The Italian Army Knife, a very SILCA take on the traditional multi-tool. We've addressed the things that frustrate us with conventional multi-tools, while keeping the layout that fits conveniently in the SILCA EOLO Wallet or MATTONE. The mid-length tool design is long enough to provide access to recessed fasteners, but short enough not to experience twist or damage under moderate torque as can happen on longer tools. All tools are forged rather than bent from hex stock. While this method of construction is more expensive, the value is unquestioned during a road-side repair. Mid-length tools also allow us to position the tools within the same plane, reducing the thickness of the overall package by half. Double-chromed tools and fully stainless steel hardware and bushings guarantee a long life without corrosion (the number 1 killer of multi-tools is corrosion). Forged aluminum sidebars contain rare-earth magnets for holding a spare chain connector. - Forged and machined sidebars with integrated chain-connector storage. - Nove (No-vay) 9 forged and plated tools: Hex 2/3/4/5/6/8 +Torx 25 +PH2/Flat - 8mm adapter connects to the 5mm hex for optimal use of space. - Stainless steel pivot hardware - NOVE- 79 grams
