Crikey, they are big! Would they be for framing? Suspect they may split without ferrules? But you will know a lot better than me David
they won't split soon, but it's possible over time they could be driven to split.
the bolster is large on these, though - I think handles of this type would be DOA in any type of wood that splits easily.
I would guess the intent at the time was that you'd choose a good wood for the handles, and breaking, though infrequent, would be easy to address. You just get a blank, square the end of it, install it on the chisel and then trim it.
I prefer the 19th century style with the bolster, though. If I come up short on a forge weld, or something breaks the weld later, there's a good strong band of brass preventing the handle from creeping very far down the tapered tang.
As for use, I'm guessing this is kind of a refined hatchet for an all hand worker. Like trimming corners off of something that will be round (legs, etc) or whatever else. I've never seen something like it before the FWW article except for gouges - it's impractically wide as a striking chisel, but surprisingly good if stuck in the shoulder and leaned on to trim. I'm curious, but not curious enough to look further - to find out if the williamsburg blacksmith just made it up more or less.
the seaton chest shows pretty large firmers with big bolsters and tangs, but they aren't paring or push length like these. These look like giant sledge hit chisels, but excel instead at paring and being heavier than the typical paring chisel (I like to make those, too) that have some spring.
Your question is an interesting one, though - aside from me having some pucker factor about such a big forge weld of hard tool steel standing on its own, I wonder if discretion in use made these hold up well. Of all of the chisels in the book, some are broken on the bit end, but none on the handle end. What i don't know without actually reading the book

is if any were remade.

In terms of proportion, I just had another look - the seaton book has chisels the width and with a handle and bolster similar to these, but they're around 3" shorter - which would make them awkward to lean on, and not awkward to mallet. I mallet tested these to see if the edges are as good as I'd hoped (the first two not, thus making two more), and they are really awkward to mallet (shoulder strain after not that long).
there are folks much better about the history of the tools than me, though. I just needed some proportions to look at so they wouldn't look like they're made by an amateur.
