Brian and Carlo both used their own machetes yet the way they slashed the tatami mats produced different results.
One lacked technique while the other lacked force. However, it was safe to say they lacked in both departments with a small deviation.
In Brian's case, he easily chopped the tatami mat in half but it didn't stay in place, and even if he managed to perform a double-cut by quickly brandishing his weapon, all it did was make a small cut and send the upper half of the tatami mat flying.
In Carlo's case, he went a little too steep with his angles and once he slashed down, he didn't manage to chop the tatami mat in half. It just looked like a broken tree trunk where the upper half was just hanging by a small bit.
They didn't immediately react as they just looked at their results with a pensive expression. Some of the people watching were giving the same expression as well but the majority wanted to test themselves immediately.
