When our Dad's were boys, Tee handle tap wrenches had independent jaws that closed by a internally tapered nut. They gripped the square securely. Junior process engineers and skinflint accountants came up with the cross sawn body to save a dollar, and our mechanical civilization has never been the same.
And now the chinesium versions so roughly turned, all your grip is used up overcoming that friction, without closing the fingers much.
I predict, soon a few companies will bail that particular offshore supply, leaving behind nothing but "Made in..." stickers. Then we class action sue them into oblivion.
