The Benchmade Griptilian family knives, known for its well-rounded performance as an everyday carry, just got a little bigger! Introducing the 551-1, the 556-1, the 550-1 and the 555-1 Griptilian which will each feature CPM-20CV blade steel. CPM-20CV is the latest addition to the Benchmade portfolio of steels and offers excellent edge retention and great corrosion resistance which are typically hard to find in one steel. A powder metal steel that takes a fine edge and maintains it, 20CV is a great choice for someone looking for low maintenance and superior cutting performance. In addition, to brand new blade steel, the latest additions to the Griptilian family will feature contoured and tetured grey G10 handle scales with a blue accent and blue barrel spacers.
