I never was one to say one tool for every thing. These are the multi-tools in my arsenal. The corkscrew is on my folding church key. I have actually use two multi-tools at the same time when working on something. It was easier than opening my shell on the truck, rolling out the sliding bed and digging through the Pelican cases.
The Schrade, I found walking my dog Miss Kittie in the alley behind where we lived while on contract in Kalifornia. It was covered in rust. Must have been in a rusty tool box and someone dropped it while dumping in a dumpster. Stainless just does not rust. It cleaned up nice. Nice to use and if you search the web you will find they are cheap to own.
Enjoy.
