Just in case you need it.

Go to Home Depot or Lowes.
Go to the kitchen cabinet department and get a sample ship of laminate surface material, ideally a smooth type, not textured.

Put that sample in your wallet.

If you need a knife, break off a corner of the laminate sample. You'll instantly have a scalpel-sharp blade that's fairly durable.

I learned this as a result of a little shop mishap I recently had with some laminate materis, soon followed by tests on rope, leather and other materials. It's a remarkable material, laminate finishes, and I'm still stunned at how sharp it is.

You mean some of these TSA's they hire can actually type?

Doesn't that tend to make them overqualified?

That is why LEO types monitoring secure areas like courthouses are now trained to bend or flex wallets and checkbooks...
