You brought this up in the ratcheting screwdriver thread.
AFAIK, the current Ivy Classic line is Taiwan sourced. Or at least those that I have seen.
The Ivy Classic ratcheting screwdriver is the same as the current MAC offfering (yes, I've done the side by side) and is very capable for the $20 USD they go for , for the Ivy Classic.
I have the Taiwanese made Ivy Classic ratcheting screwdriver and love it. Not the same as S-O but , obviously , same as MAC.
At $20 well worth the price. I'll ask if my local supplier can order one in for you where I bought the one I have.
Has knurled shaft like S-O and the rest is a MAC clone. Win-win.
The gold collar I cut off as it is a fluff piece and reveals the std. magnet in the shaft like every other pro driver.
Hidden gem.
