First Look: GiantMouse Riv Folding Knife

posted on December 27, 2020
GiantMouse Knives released the Riv, a new model in the company’s ACE line of folding knives, proving yet again that good things do come in small packages. The Riv takes its inspiration from the lines of Giant Mouse’s Biblio knife, but with a completely new design that come with its own feel and expression.

The knife’s designers, Jens Ansø and Jesper Voxnaes, grew up out in nature working the forest and doing chores around the house. They were taught to carry a fixed blade and a small folder. The fixed blade will perform most of the cutting tasks, but the folder should be kept razor sharp for finer tasks and be your back-up, if the fixed blade is lost or dulls. The compact Riv fills that role perfectly.  

Like so many other blades from GiantMouse, the Riv takes its name from a popular watering hole. In this case, “The Riv” is an historic local dive bar in East Lansing that was frequented regularly by GiantMouse CEO Jim Wirth while he attended Michigan State University in the second half of the 1980s. The bar is still a local landmark today  

The Riv is available in Titanium, Brass, and Green Canvas Micarta. While the green canvas Micarta version will be sold through dealers, the brass and full Ti versions are GiantMouse exclusives, and will only be available on the GiantMouse website. All models feature Elmax blade steel, ball bearing pivot, and titanium frame lock.
