Monday Mystery, ETF Logo?

We've covered the St Catherines, Ontario based ETF Tools company before. They made a wide variety of wrenches, hammers etc, though we haven't seen if clamps were part of the line,  These pictures were sent to me, wondering if the cast-in logo was a variation we hadn't seen before. It looks like an E, a T and an F are stacked up upon each other inside a diamond. There are already variations seen in the ETF logo... ahhh, another little mystery.
