Don't stash this stuff away...use it! What would you rather have at hand in an emergency - some shiny new gadget that you last handled eighteen months ago or ol' Reliable (the stove, knife,light, or whatever) tht you have been employing on your outdoor excursions regularly for the same period?

Nearly everything needs maintenance, resharpening, or whatever. That is all part of the true mastery of good tools and equipment.

I agree about the propane adapters for Coleman white gas stoves. I went to propane via the adapters years ago, and much prefer it to liquid gas. I keep the tanks around for increased versatility.

You say you don't camp out, or hike, or spend nights outdoors. My condolences!! There is still time.
