Com: Shredder joe : Testing our shredding crushing machine with some rough scrap metal..

Com: Trung: Where is the sledge hammer being crushed?! That is the only thing I ever wanted to see in life! Thumbs down for misleading thumbnail image!.

Com: Shocx : After watching maybe 20 or 30 or 50 of these videos... the one thing we all wanted to see was watching that beautiful piece of hammer getting crushed (or the machine breaking trying to do so..) but your clickbait robbed us of that opportunity... YouTube will not forgive this... This shall be remembered.

Com: skott:   Your version of hard steel is very different then my and probably most peoples version of hard steel thumbs down.
