Here's my Tool Kit. I also carry a twenty year old Mini-Buck 350 multi-tool, which doubles as my kitchen knife. At 30 g (1.1 oz) it is a gram counters dream!

Over the years I have parred it down and cobbled together bits of kits like the 25 g pedal wrench from a 290 g Alien multi-tool and the two tiny tire levers (10 g total) from a Topeak 192 g Rocket Ratchet set.
