Gut Knife Tiger Tooth Factory New is a Covert CS:GO knife skin that was added to the game back in January 2015 as a part of the Full Spectrum Update. The Tiger Tooth Gut knife can be obtained as a random reward from three different CS:GO cases, these being Chroma Case, Chroma 2 Case, and Chroma 3 Case. The knife skin comes only in Minimal Wear and Factory New exteriors and these can have the StatTrak technology attached to it.
The Gut Knife Tiger Tooth is designed to have a thick blade with a cutting edge on one side and a hook at the tip of the blade, thus its name. In terms of design, the blade has been anodized with orange and then had a tiger stripe pattern etched into it.
When it comes to the price, The Factory New version is usually worth around $159 with the StatTrak version being slightly more expensive.
