Another vote for 2 separate wrenches.

At the low end of this torque range I find it hard to use a beam or a ratcheting click style torque wrench like the TW-5.2. You can easily get to about 8-10 Nm with a screwdriver or T handle. I use a CDI TorqControl Wrench in this low range. This is also a common range for firearms, so there are a lot available if you look in gunsmithing tools. A buddy who is a gunsmith uses a Wheeler torque screwdriver for non-critical items and a Wiha for the delicate stuff. I got the CDI from him after he tried it and didn't like the T handle style. Above this range I use a GearWrench 85060.

Park makes good tools but I don't like their torque products. The ATD-1.2 fits nicely in the hand but I don't like that I need a 5mm wrench to change torque ranges. And the TW-5.2 is okay but 1) the scale window is sort of small, and 2) it is a 3/8" drive. All I usually use with it is 1/4" insert bits on these smaller fasteners. I had a 3/8" to 1/4" adapter and a 1/4" insert bit holder on it all the time, where the GearWrench just needs the 1/4" insert bit holder. It just makes it one more thing to misplace.
