This used CIVIVI Mastodon captures everything we love about the Bullmastiff design and takes it one step further with a more traditional cleaver-style blade, complete with CIVIVI’s trademark hole. Available in two sizes, the Mastodon is perfect for everything from everyday carry to tactical applications — and this full-size model doesn’t disappoint.
 
The broad, flat-ground cleaver blade is crafted from durable 9Cr18MoV stainless steel and finished with a rugged stonewash that hides wear. While cleaver blades are often associated with chopping, their growing popularity proves they're excellent for a wide variety of tasks, from food prep to heavy-duty utility work. Plus, that intimidating look doesn’t hurt!
 
Paired with a stout, ergonomic Red G10 handle, the Mastodon offers excellent control and comfort during extended use. This used knife shows light signs of carry but remains in excellent working condition, making it a great opportunity to snag a versatile performer at a fantastic price.
