I thought of this last week while on the road, and then spent the last 3 days trying to remember it.
Super Glue.
This is an item that should be in every first aid kit. The risk of injury requiring medical attention for a serious cut warrants the inclusion of this little tube of wonder. If you are ever cut bad enough that you think it should be stiiched, just clean it and glue it closed.
There is a reason why super glues instantly bond to skin and nothing else. Of course it is recommened to use an FDA approved medical super glue such as Dermabond.
