“The serrated edge won't stop any kind of 'shin hit' on the tow bar.
For a start the serrations are only 6 mm long.
The shin guard LOOKS LIKE it would do the job of reducing shin injury, but won't be effective.
If you want to play around with the shin-guard, just try banging it edge-on against a right-angled edge of your desk or work bench and you'll immediately see it is not effective, BUT, it looks like it would be effective.
A response from Award would be nice.
