In 2005 Wenger created the first ergonomic Swiss Army Knife, making resourcefulness more comfortable than ever before. Now the EvoGrip expands on that advance. The four major areas of contact your hand makes when utilizing the EvoGrip S557 Swiss Army Knife are embedded with non-slip rubber increasing its safety, performance and efficiency. EvoGrip Swiss Army Knives are truly a symbol of our unwillingness to be satisfied with a classic – even after more than a century. With 13 implements that perform 19 functions, the EvoGrip S557 Swiss Army Knife is as useful as it is advanced. Keep all the tools on your Victorinox EvoGrip sharp and well-maintained with a compact and convenient pen-shaped diamond grit sharpener from EdgeLogix.
