I should probably introduce myself a little, having just showed up a while ago looking up data on my Leatherman. Anyway, I'm 76 and I've been around tools for a long time, and I tend to collect stuff, and I thought a couple of hammers might be of interest here. I have lots of hammers. A significant but not complete collection of those that never got rehung hangs on one of my outbuildings. [ Quoting of attachment images from other messages is not allowed ] I've got way too many hammers of all sorts, from the tiniest ball peens to the sort used to drive circus tent poles, but thought tonight I'd feature a couple of the strangest. First is a short-lived Estwing model, which apparently didn't sell well. Too bad because although it looks bizarre it is very tough and nice to use. It's modular in construction, and head portion is cushioned a little, so it's nice to hit hard. The second, found long ago at a sale, has a hand forged head and hand made handle. Some long ago blacksmith made this thing, and now I'm a bit reluctant to use it, but it's beautifully balanced, and if some ultimatum came down that said I could only take one hammer with me, this would likely be the one.
And more....
Nail placement seems a stretch, because framing hammers with magnetic nail holders are pretty common, and they work well to put a nail in place with a single blow.It does look cool and I'd love to have one. If I did, I'd consider it a likely candidate for slate roofing, where a sharp point would be used to put a nail hole in a slate, which it does quite nicely, and the rest of the claw would still be available for pulling old nails. But what its actual use is, I'm uncertain.It appears to have a label still on the handle. Is there a possibility of a manufacturer's name or model number etc.?e.t.a. I just looked again at the picture, and I don't think it would do so well for slate roofing after all, because, although the prong is pretty pointed, it's still a bit flat. For poking nail holes in a slate you really want a sharp, round point. In the past I've used a fencing tool, but later found a body hammer with a pointed peen which I sharpened a bit more. But this does lead me to wonder whether the hammer in question would work well for fencing with the point good for pulling staples.FURTHER e.t.a.....I just looked around, and though I did not find quite this hammer, I did find something billed as an electrician's hammer which has one elongated claw, made specifically for pulling Romex wire staples. This would also explain why it is, though narrow, a bit chisel shaped rather than round. So that's my best guess now. If you've ever had to pull Romex staples, the design makes a lot of sense.
