I just received one of the Weber polished head razors from the latest batch, (December 2012) and noticed the the center threaded post is a bit wider, threads are thicker and the threads go down farther on the post, compared the to earlier batches of Weber polished head razors. I like the new threaded post because the handle threads more securely with less wobble than the older design. I think that was the last thing that needed to get changed and I think this razor is great.
