Ruko Shark 3.5" Assisted Opening Folding Knife Clamshell

Ruko lists this one as a spring assist folder: start the 3.5 inch stainless blade moving and the spring takes it the rest of the way open. The handle is aluminum, so the knife stays light for something that lives in a pocket all day.

Assisted opening earns its keep one handed. Holding a rope, a strap or a fish in one hand while opening a knife with the other is the situation people buy these for. The rest is straightforward: a flat profile that does not print through a pocket, a handle that fills the hand well enough for real cutting, and a blade that comes back on a stone without a fight.
