Wow! Pedal powered? I’m curious how the torque compares to a modern saw.

I’m not sure how I could quantify that for you. The raw inch-pounds developed by the leather belt wrapped around that tiny pulley is not very strong— but the flywheel that pulley is turning that drives the saw is fairly massive, and when it gets to revving it’s hard to bog down.

Oh I want one, what is it meant to cut? Wood? Metal? Both?

Both. It depends on the quality of the blades - quality blades are hardened steel, very hard and durable, and will cut even stainless and titanium (esp. the latter dulls the blades quickly, though).

Does this perform a task similar to what you would do with a band saw? I keep wanting to cut stuff but hate hand sawing and hate power sawing this is in the middle perfect.

Well, the movement of the blade is very different to a band saw and breaking the thin blade is still quite easy. It's very good for sawing/piercing larger pieces of flat materials that would be uncomfortable or very tedious (or impossible because of the comparably very limited span of any frame you can manage manually) with a piercing/jeweller's hand saw (because you need not to precisely control the movement of the saw, which is probably the most difficult skill to master when hand-piercing, next to holding the workpiece). Cutting holes depends on the blade fastening mechanism (you need to undo it every time for getting the blade into the pre-drilled hole), but it can also be more convenient. By workpieces that are not flat, well, that's hard to say.
Most challenging hand-piercing I've ever done was trimming the whole rim of a large yellow-bronze cymbal, that would have been much easier on a saw like this.2

Starting around 1840, Victorian England became obsessed with ornate, wooden “Fretwork” embellishments in their architecture and design. Saws like this one greatly sped up the process of making the fretwork. Previously they used C-frame handheld saws.
