I bought an Okuma LB-15 about 15 years ago. The tools were held into the turret with two screws that simply clamped down on the toolholder. They clamped down backwards, meaning that the head bore on the toolholder. If memory serves, the head was 1/2" across. The Okuma came with an open end wrench for those screws. It had to be an open end wrench because you couldn't get to the head any other way.
The wrench was black and it just had Okuma forged into the shank.
Now there is something about that tool clamping arrangement that causes those screws to become ungodly tight during use. After a couple of years the wrench had sprung open to the point where I had to replace it. I went into the Snap-On van and told the guy that I needed the bestest 1/2" open end wrench he had. Which he sold me for typical $nap-on pricing.
The Snap-On wrench sprung open almost immediately. It was nowhere close to the ugly black Okuma wrench in performance. I've often wondered where Okuma got those tools.
Anybody know?
