I use this for minor repairs to my HMB/Buhurt (steel/titanium armour). It's heavy enough that I can get the horn into a helmet and peen down rivets without any trouble. It's light enough that it can go on and off the shelf between uses. The surface was flat and it's been smacked dozens of times with a mallet without any serious dents. For the price, I can't imagine doing any better than this.
