OK. brand chisels are yet another mystery brand for me. They do not seem very common. I have only seen the set below and a couple of others so far.
I believe that the OK. brand has a period after the “OK” to get around trademark restrictions. “OK” by itself would have likely been difficult to trademark because of it’s common usage. Carl Kammerling did something similar with its “C.K” brand chisel, placing a period after the “C”.
The OK. chisels are nicely made and pleasing to look at, as the set below illustrates.
The chisels have attractive beech handles. The steel hoop at the top of the handle is held in place by two deep dimples punched through the hoop on opposite sides. The brass ferrule has fairly coarse vertical lines spaced tightly together.
The label colors are shown accurately — yellow background with dark teal green oval outlines and lettering.
The three widest chisels have the stylized “OK” and “MADE IN SWEDEN” stamped on the blade. The next narrowest has “SWEDEN” stamped on it and the most narrow chisel has nothing stamped on the blade.
