Added pics and specs to KS-1006K Kershaw Amphibian – Kydex Sheath
The Amphibian provides all the strength of solid corrosion-resistant 420J2 stainless-steel from tip to pommel, but with a skeleton handle design to reduce weight. A co-polymer insert in the handle assures an excellent grip. The Amphibian blade is sharpened on both sides – one side offers a standard edge, the other a partially serrated edge.
