I've kind of avoided posting in this thread because I think @vincev said it best. There are too many tools that I like to use to do the many jobs needed to restore a bike. But in thinking about it more, I think this non-glamorous tool kinda fits into this thread for a very specific personal reason. This Lincoln Lubrigun grease gun is the only grease gun I've ever had all of my life. I believe it was my fathers and I used it growing up for my motorcycles and bicycles and I've continued to use it. Since it's the only grease gun I've ever had, I'm fairly certain that I've used it on every bicycle that I've worked on in my entire life. There aren't many tools I can say that about so this one gets my nod for the favorite tool thread .
