A heavy knife is a type of large, sharp blade used for cutting and chopping. The term can refer to a variety of different knives, including the MACHETE (7 letters), BOLO (4 letters), BOWIE (5 letters), and CLEAVER (7 letters). Machetes are long, curved blades used for clearing brush and chopping wood. Bolos are similar to machetes but have a more pronounced curve. Bowies are large, fixed-blade knives with a clip point and a crossguard. Cleavers are large, rectangular knives used for butchering meat.
