This multi-tool ticks all the right boxes for functionality. The separate hex keys are great and the addition of a small blade seems like it'll be useful. Also, the chain keeper is a bonus.
I've not used it on-trail but tested it in the shop and the quality of the tools is on par. While generally I aim for a minimalist on-bike tool kit, this will likely end up in the MTB bag for longer, more isolated rides when you can't just coast or huff-it back to the lot in case of a more major issue.
