This Otter slip joint has a titanium handle. The Terrain 365 Otter is a Barlow-esque slip joint knife with classic design, but modern materials. The blade is made of Terravantium, and it includes a shackle on the back for a lanyard if you like. Add a precision built slip joint to you collection with the Otter! Terravantium is not steel. It is a dendritic cobalt alloy. It is non-magnetic, cannot rust, and has superior edge retention to any steel. Note: Terravantium is more brittle than steel. If you chop, pry, or do other hard tasks with the knife, the blade may break. Titanium not your thing? Check out the other flavors coming soon!
