You have done it now. You have asked the purpose of the nib- the start of many a fight on hand tool forums. Some will tell you it is like a gun site, others will claim it is used to notch the start of the cut. Those people are totally wrong. It is simply a vestigial remnant of a decorative element used on saws from antiquity.
As for the saw I can't tell if the handle is large enough for an adult. It looks too small and crudely made. So possibly a child's saw. If meant for an adult, it looks like a table saw. The narrow width allows a person to saw out round table tops.

Everyone knows the nib is for scratching your back without the fear of drawing blood with sharp teet.

Actually, we like the nib question - the arguing is rarely bloody.
Just don't go to power tools and ask "what is the best tablesaw"?

I think you have a very old panel saw that's been sharpened many times. I also think the handle has been replaced. Disston added the nib (spike as you refer to it), and nobody really knows the purpose. Perhaps just decorative. Is there a medallion on the other side of the handle where the screws are? If so, take a pic of that and post it. That would help in ID. Otherwise, I think you have a generic hardware store saw. Disston's handles on their panel saws were attached with more screws than just the two on your saw.
