If it is very similar, it shouldn't be patented as it's public domain technology.
You should definitely submit this to the USPTO as a prior art they may not have considered. They are able to re-open examination for this sort of thing.
- easytiger 12y agoErr, also, a err, axe?
- esquivalience 12y agoHaha - yes, but it's probably safe to assume they knew about that already when the patent was granted and they overcame it. Perhaps because it's solving a long-standing problem or because the axe is a very different application of force, or something. The above is basically a sports bat so might be close enough to warrant a different perspective.
