about a year ago. The tools are made from S2 or CrV steel. Best of all, the stuff is made in Taiwan. For $60.00 the set is remarkably good value, IMO. Although I've used the tools quite a bit, there's barely a scratch on them. I checked out my local Total Tools and I reckon the Aldi set is approximately equivalent to a set in TT that sells for around $130.00.
For the record: The socket set alone makes it great value. As far as I'm concerned, the other tools are just a bonus.
