I just use a piece of ply with 'v' notches at each end.
Cheap, don't think the wife will ever notice where I got it from.
Think it floats (the ply does but not sure when loaded with cord . . . hmm, will have to test!),
Holds lots of line,
Can use in emergencies to cut bait up on,
And if you are swallowed by a croc, make sure you are holding it when sliding down throat as you can use it to prop croc's mouth open so you can crawl out and escape.
People whack me with it and tell me to settle down.
