Review on SK Hand Tool 77100 Micrometer: Precise and Reliable Measurement for Optimal Accuracy by Raji Bentz

This is a serious professional quality tool! Revain price is $100 less than SK website! I was so pissed off with cheap Chinese torque wrenches that kept breaking bolts because they weren't accurate at all. I ended up spending the money on a quality torque wrench and this one is amazing. The locking mechanism is great, the setting can only be changed by pressing the locking ring (and this will never happen accidentally during use). With this button, you can't accidentally turn the knob and mess up the mood. It comes with a very detailed certificate of calibration with accuracy at multiple settings from 10 to 100 lbf in right and left directions. I am now confident that I will never mistighten another bolt again.
