Very interesting, I have looked closely at the pics, and am wondering what sort of steel is the pin? Rated? Billet? Mild?
I realise the strongest points are the closest to the "block", so therefore should snatch most light to medium bogs. And if this "pin" failed it would become airbourne, but, I suspect more likely to go either outwards ur upwards, not towards the vehicle being snatched, unlike a bow shackle on the end of a snatch strap.
