I have a pretty minimalist tool kit. I've ditched the multi tools because they just weigh too much and have tools that I don't need.
This was the tool kit that I used on my recent CO Trail trip.
Patch kit (I run tubeless but carry two spare tubes) 4 backup matches with needle and dental floss (saved my butt when I got a big sidewall slice) Drillium tire lever (25% lighter, 100% weaker)
CRKT RSK Mk5 knife, tools bolt to handle for use.
2.5 3 4 5 T25 bits (this covers every bolt on my bike, will be different for everyone), spare bits are stored in patch kit. FiberFix Spoke with spoke wrench.
Not pictured, Specialized Chain tool that doubles as stem cap, and holds Quick links. Mini pump


Slice in sidewall I sewed up with floss, lasted 160 miles of CO Trail, and I'm still running it.
