This is unquestionably a great cleaver. This Extrema Ratio cleaver has the heft and strength needed to get the job done. It has a wide blade and a thick spine. Plus it has a distinctive, unusual finish that claims attention.

Like all cleavers it is versatile. Because of its thick, stout blade it is capable of doing the following:

use the blade's heavy weight to chop through thick meat, bones and cartilage

use it for mincing, heavy vegetable and nuts chopping

use the side of the blade to crush garlic bulbs, fresh ginger, etc.

use the wide blade to transfer food from your chopping block to wherever

Obviously utilitarian but handsome. Obviously a serious knife. Obviously made by Extrema Ratio with all the quality and details that go into their knives.


The Extrema Ratio cleaver has the wide, thick blade that identifies it as a cleaver. Excellent weight and strength. Has an interesting, eye catching laser engraving on the satin blade. Has an extended area with a large hole so you can hang your cleaver on a hook to keep it handy.


The cleaver handle is made of Forprene and has a “rubbery” feel. Comfortable to hold. It has the Extrema Ratio distinctive signature handle. It is an ergonomic handle design that gives you a firm grip. Performs well with wet hands.


The cleaver has a quality, heavy-duty Cordura sheath. This sheath is only meant to provided maximum protection when you are carrying or storing it. Protects the blade as well as your hands.
