The Genuine Innovations Flat Stack Mini Tool has had a home in my pocket since last Fall. The Soma Fabrications Lo-Pro 8 Pocket Tool is a even smaller version.

 Both tools are constructed from a high-quality steel. Each bit is formed on a big square base which makes using these tools very solid, much better than most mini-tools and rivaling the effectiveness of much larger shop wrench sets.

Each tool measures just 7mm thick by 27mm wide, about the same as 4 quarters. The 79g Flat Stack is longer at 72mm vs 55mm for the 57g Lo-Pro 8. The extra length does give the Genuine Innovations version more leverage though both work well for most trail-side repairs and adjustments. Included tools are: 2, 3, 4, 5, 6mm hex wrenches, T25 torx wrench (disc rotor bolts), flat head and #1 philips head screwdrivers. Lacks only the 8 or 10mm hex used by many current crank sets. 

I carry one in my jersey or shorts pocket where I can access it quickly. Weight and size is makes it unnoticeable otherwise. One also lives in my pants pocket where I find myself using it nearly everyday, mostly for non-bike purposes.

 Genuine Innovations Flat Stack Mini Tool sells for $19.99.

MSRP for the Soma Fabrications Lo-Pro 8 Pocket Tool is $14.99.
