"when Bhimasena and Jarasandha were heavily striking each other with their clubs on different parts of their bodies—namely the shoulders, arms, collarbone, chest, thighs, waist and legs—their clubs were torn to pieces"

Krsna, The Supreme Personality of Godhead

When two elephants fight together in a sugarcane field, each of them snatches a stick of sugarcane, holds it tightly in its trunk and strikes the other. At that time the sugarcane becomes smashed by such heavy striking. Similarly, when Bhīmasena and Jarāsandha were heavily striking each other with their clubs on different parts of their bodies—namely the shoulders, arms, collarbone, chest, thighs, waist and legs—their clubs were torn to pieces. In this way, all of the clubs used by Jarāsandha and Bhīmasena became ruined, and so the two enemies prepared to fight with their strong-fisted hands.

Krsna Book 72:

Bhīmasena and King Jarāsandha engaged themselves in fighting, and with their respective clubs, which were as strong as thunderbolts, they began to strike each other very severely, both of them being eager to fight. They were both expert fighters with clubs, and their techniques of striking each other were so beautiful that they appeared to be two dramatic artists dancing on a stage. When the clubs of Jarāsandha and Bhīmasena loudly collided, the impact sounded like that of the big tusks of two fighting elephants or like a thunderbolt in a flashing electrical storm. When two elephants fight together in a sugarcane field, each of them snatches a stick of sugarcane, holds it tightly in its trunk and strikes the other. At that time the sugarcane becomes smashed by such heavy striking. Similarly, when Bhīmasena and Jarāsandha were heavily striking each other with their clubs on different parts of their bodies—namely the shoulders, arms, collarbone, chest, thighs, waist and legs—their clubs were torn to pieces. In this way, all of the clubs used by Jarāsandha and Bhīmasena became ruined, and so the two enemies prepared to fight with their strong-fisted hands. Jarāsandha and Bhīmasena were very angry, and they began to smash each other with their fists. The striking of their fists sounded like the striking of iron bars or like the sound of thunderbolts, and the two warriors appeared to be like two elephants fighting. Neither was able to defeat the other, however, for both were expert in fighting, they were of equal strength, and their fighting techniques were also equal. Neither Jarāsandha nor Bhīmasena became fatigued or defeated in the fighting, although they struck each other continuously. At the end of each day's fighting, they lived at night as friends in Jarāsandha's palace, and the next day they fought again. In this way they passed twenty-seven days in fighting.
