Can of Halt, Leatherman tool. Both were generally useless weight.
This somewhat surprises me. I can see the uselessness of a can of halt, but I find a Leatherman invaluable. The pliers come in extremely handy in many cases and I use the knife almost very day. The Philips and regulars screw drivers come in handy on occasion. But each to his own.
I think a Leatherman is overkill for a bicycle. My mini-tool has all the tools that a Leatherman would have except for the pliers, and it weighs less, so I have a separate small folding pair of pliers for that which came with a pair of scissors which are very handy to have...but when I went to look for it just now, which is my saddlebag, the saddlebag is missing off my bike? I never remove it because I have saddlebags for each bike, just move things from one bag to another if I need something in one that's not another. So I'll have to wait for it to warm up a big more and go into the garage and clean up and see if by chance it's somewhere other than where it's supposed to be.
I use a separate knife, I don't particularly care for the one that came with the mini-tool, so I carry a CIVIVI Baby Banter, it's not the most expensive knife in the world, but things can get lost when bike camping, so I didn't want to lose a $400 knife, so my budget was under $75, had to be resistant to corrosion since it was going to be used outside and with all sorts of food; I got it in red so it would stand out if it fell onto grass, it had to be small and lightweight, and very sharp plus stay that way, that CIVIVI knife was made of Nitro V steel, suppose to be highly resistant to corrosion, and the best part was, it cost under $55! SOLD! I'm not a knife/steel expert, but after reading a lot on the internet that one seemed the best for the money that I could find, and so far it's worked out great for this last season. I don't hammer on it, or chop wood, though I can whittle wood shavings to help start a fire. Never heard of the brand before but they are made in America...well at least the steel is, not sure about the rest of the components, you know how today's world is.
