If you want a portable combo tool; I recommend from ownership the sunlite 3 in 1 (chainwhip, lockring tool, universal pedal wrench) tool really handy and perfectly sized for torque and portability.
Combo tools are handy but if you want something that lasts way longer and performs easier and better, spend the extra money and get shop quality tools at home like the park tool sr1/2 (2 is way better in my opinion) and a hozan lock ring tool.
