Maximum square drive is awesome.
A family member works for Canadian Tire corporate and filled me in on quite a few things.
The brand "Maximum" is not related to "Mastercraft", other than both being CT house brands. I've called it Mastercraft Maximum for years but I was recently told they have disconnected the brands.
I'm pretty sure the Mastercraft Pro stuff was made by Stanley but the new stuff is made by multiple manufacturers and, apparently, it changes over time, even with the same model of product. CT owns the designs so they can do that.
Maximum, particularly the square drive and wrenches, is really good stuff. I believe you will do well with those tools for the rest of your life.
Pass... and high marks, at that.
