Worthwhile Tool
When traveling by airplane, passengers are not permitted to bring on board a number of items that are typically utilized in their day-to-day lives. The fact that this is the case does not imply that the things in question are inherently harmful or unsuitable for use, but there is a right time and a proper location for the application of certain things.
Also, this rusty shovel, rake, or hoe tool is probably not going to be allowed on the flight with you, as we are pretty sure of that. Why would anyone even attempt to bring something like this on board a plane with them? With all due respect, it does not appear that this is a useful tool that should even be saved.
