Wierd looking Shunt....

If it has solder and bite marks then the calibrator was having a bad day. :-DD
Gyro:
I wonder if the solder blob is where they squeezed the cutters a bit too hard and actually cut through! :D
Yes, the better quality shunts are filed or ground over a long length for uniform dissipation and accuracy. They also have crimped areas near the ends to ensure that they sit at a predictable height (wire length) above the PCB. Fluke are probably best (in a handheld anyway), they weld a U shaped piece of wire across each end of the shunt so that they can do proper 4 wire Kelvin sensing.

Can you get your money back? Then get yourself a Brymen or even a UNI-T.
Edit: It seems they are actually a German company out of Bremen. That looks suspiciously like a stenciled cheap Chinese meter.
If you don't mind y asking, how much was it?

Yes, I will get my money back. I paid 120 US, and now its at 178 US.

They have the exact same meter on the front page, lower down.

That's shunt tuning for calibration. Dents make the shunt resistance higher, blobs of solder make the resistance lower.
