The first batch sold out pretty fast, maybe even sold out in pre-order, ikd. I stupidly decided to wait and see reviews before buying, so I didn't get one of the originals. The latest batch has a different lock bar that I don't like. It doesn't have the step in it like the one on the original, and there are also a few reports of the bar standing proud of the back of the handle. Link:

As far as availability, it appears like this particular knife may be subject to limited availability throughout its lifetime. Since we don't know who's making them, I can only assume it's either a smaller company with limited production abilities or a larger company that only does batches when they can without interfering with their own products. I hope they go back to the original specs on the lock bar on the next batch (finger crossed).
