I bought a couple of the TSA Swiss Army Knives off separate eBay sellers. I paid $12 for one and $15 for the other with free shipping.
You might take a look and see what they are going for. The more do-dads the more they cost.

I prefer the Vitronox Officer Suisse. The one with the Saw Blade and a phillips head screwdriver instead of the cork screw.

I thought that I read somewhere that some Airlines were allowing the Swiss Army type knives on board.

Note I had to use the saw on the knife over the weekend to make an unplanned cut through some Dry Wall. It save me a trip do the store to buy a cheap dry wall saw.

Also once on My job as a mechanic I was out in a 40 acre yard working on a vehicle and had to cut a 2x4 in order to use it on the job I needed to finish and I cut through the 2x4 with the Swiss Army Knife saw. A lot of work but it worked much better then think it would have.

I have had a lot of other incidents were having the saw blade saved me time and effort.

Likewise the phillips head screwdriver is handy to use for light weight jobs like tightening up the screws on Light Switch Covers and Electrical Sockets saving you from having to get a screwdriver from your tool box.

On the other the Cork Screws on those knives does not work as well and are a PITA dealing with a tight bottle cork even if they are better then nothing.
