Yes, Bob, I did, in fact, coin the term, "hammer" several years ago (the term "hammer stone," was first used by Adam Hupe - though I never understood the point of adding the term "stone," especially since at least 2 hammers are irons). I referred to them as "hammers" because they had nailed something. As mentioned on my Hammer Page, Walter Branch published the first listing I am aware of of meteorites that hit things. It was originally hosted by Walter, himself, but I believe it is now hosted by the IMCA. Some interesting debates are more along the line of whether or not a fall qualifies as a hammer if: 1) it hit a road, and if so, is it only if it was a paved road? (I, personally, do not consider said falls of either type to be hammers, but it is reasonably debatable). 2) Is Nakhla a hammer, since Kevin Kachinka pretty much demonstrated it did not strike a dog as reported... the reason some do consider it a hammer is that Ron Baalke made a case for at least the remote possibility that it did. 3) Is Monahans a hammer - as it was reported to have hit a "basket ball court?" I, personally, do not consider it a hammer, as it did not, in fact, hit a basket ball court. In fact, the "basket ball court" was actually just a hoop nailed to a power pole or over a garage door. The point at which the stone struck was actually a dirt pathway immediately adjacent to where the kids were playing basketball. (apparently there are no paved side walks in that particular neighborhood) So, in short, I do not, personally, include Nakhla or Monahans in my hammer collection, but do offer them on my hammer page with a full explanation regarding their status.
