Multi-Tool A100


The A100 broke new ground in the world of multitools when it was introduced in 1997. Available a full two years before the Leatherman Crunch, it was the first multitool to feature locking plier jaws. Also groundbreaking at the time was its one-hand-opening, liner locking knife blade. Ironically enough, the double folded sheet metal handle with one hand blade was seen again the very next year on the Leatherman Wave.


Jaws

  • Jaw shape is needlenose, with fine serrations, a gripping area, and a large wire cutter. (No hard wire notch is included)
  • Finish is bead blast matte stainless.
  • The upper jaw has a V-notch running lengthwise, to easier grip fish hooks and such.
  • Jaws are spring loaded.

Handles/Frame

  • Handles are sheet metal bent into complex shapes.
  • The lower handle is a channel shape containing four crossbolts to facilitate the locking mechanism.
  • The upper handle is bent into an S-shape, with the lock adjustment in one channel and the outside opening knife blade in the other.
  • Finish is bead blast matte stainless.
  • KERSHAW MULTI-TOOL USA is stamped onto one side. KAI PAT. PENDING is stamped onto the other.
  • An inch scale is stamped along one edge of the bottom side. A metric scale runs along the opposite edge.
  • Pivot screws are an odd mix of hex heads and knurled heads. (although photos of tools with hex socket round head screws have been noted)
