What is the minimum number of cutting devices a cave diver should carry?

Carrying a minimum of two cutting devices is a crucial safety practice for cave divers. The primary reason for this is redundancy; if a diver encounters a situation where one cutting device becomes ineffective or is lost, having a second device ensures that the diver is still equipped to handle emergency situations, such as entanglement in line or restrictive passages.

In the context of cave diving, where environments can be unpredictable and visibility limited, relying on a single knife or cutting tool may not provide sufficient assurance of safety. Two cutting devices can vary in type or size, which allows divers to choose the most appropriate tool based on specific circumstances they encounter during a dive.

This practice not only enhances safety but also aligns with the broader principle of having redundant systems in place during underwater exploration, thereby fostering a more responsible and prepared diving approach.
