Wera Joker spanners looks very similar. Havn't tried them myself, they sell them in Toolstation and Screwfix
Don't know about spanners, but the best thing I have found for rounded off bolts are Irwins:

Not being picky nose job here while pushing back thick rimmed broken glasses with one covered with xelasterplast and having sweaty palms. If the pictures are correct are you not inviting the tools to become rounded by mere or less contact area over short period of heavy use. Please feel free to slap this messenger if I'm wrong on all counts.
Could be wrong, but I think @saxavordian was referring to the part of the SPANNER that contacts the nut wearing down rather rapidly - not the nut itself.The part of the spanner or socket that contacts the nut sits on the middle of the flat and does not reach the corners so can round them off.
