First made popular in the 1880’s by George Washington "Nessmuk" Sears. The primary purpose of the design was for skinning wild game. The hump helped to control the tip of the knife, which helped to prevent from piercing organs. It can also be used to scrape fatty tissue from hides in preparation for tanning.
Today the design is used as an all around outdoors blade. Perfect for processing small wood for tinder and kindling, skinning, food prep or general outdoors use.
