The Machete is a melee weapon in Killing Floor.
The Machete is way stronger than the knife, but also way heavier.
The Machete is priced at £150 without any discount from perks. The Machete has a higher melee damage than the knife, but despite it's weight, it has a slow attack speed.
Use of the Machete is not recommended on the higher levels, however, if you find one, you can sell it for £100 around which is a good deal.
