If you're whitewater kayaking, it's not uncommon to have a knife accessible from your PFD.
It can be used to cut any ropes you might be tangled in or (worse case) cut the PFD.
In general, having a knife with you is useful in most emergency situations (and a throw rope, pin kit, plus knowledge of how to use them).
edit: Oops, this was supposed to be a response for the parent thread.
FYI: This is not really a historical low.
It was given away for free on Epic in May of 2025. So, you might already have it.
