I have purchased my share of Craftsman (three) and one KD (one) that were pieces of junk. So last year I purchased a 1/2" drive split beam from Precision Instruments. But it only torques in the CW direction. For the lone LH thread I purchased from Lowes their Kobalt torque wrenches:
1/2" Drive 59.95,
3/8" Drive 39.95.
They are made in Taiwan, but come with a lifetime warranty, and a certificate of calibration, and contain no plastic parts.
