I dont check my bags - how to get knife there?

[Dave616]

Why not get one of those lock-blade knives that uses a replaceable utility razor blade?
I'm sure utility blades are somewhat universal.

I have one of these and use it as a money clip:
Gerber EAB

I don't carry a knife when traveling to & from places like Coz, Bonaire, Curacao, etc.
Never really had a need for one...
I carry one when diving locally, but hardly ever use it.
As to foreign Customs Officers, I had one in Managua demand that I "open" my first stage, until one of his cohorts clued him in...LOL

You never know when you may "run into" mono line or a net. Not very likely in some places, perhaps more so in others.

I use my knife frequently. I never dive without it.

In my best Australian accent..."that ain't a knife...."
