Overview
The Gerber 31-000345 is a stainless steel knife with a stainless steel handle, measuring 5.1 inches and weighing 0.14 pounds. Its all-metal build points to a compact blade meant for everyday carry or light utility use.
An all-stainless build, blade and handle, trades the warmth and grip texture of other handle materials for corrosion resistance and durability in wet or outdoor conditions. At 5.1 inches overall and 0.14 pounds, the 31-000345 sits in compact everyday-carry territory rather than a full-size outdoor knife.

Who it's for
Buyers who want a compact, corrosion-resistant stainless knife for everyday carry or light outdoor use. Less suited to those who prefer a textured or rubberized handle for grip in wet conditions, since an all-steel handle can feel slick when hands are damp.
Strengths and trade-offs
Drawn from this product's published specifications.
- Full stainless steel construction resists corrosion
- Compact at 5.1 inches and 0.14 pounds for everyday carry
- Durable build suited to outdoor conditions
- All-metal handle can feel slick with wet or gloved hands
- Compact size limits use for larger cutting tasks
Performance notes
Stainless steel construction throughout resists rust better than carbon steel or mixed-material builds, making it a reasonable pick for damp or outdoor conditions. The tradeoff is grip: an all-steel handle offers less traction than rubber or textured composite when hands are wet.
