This saw has all the characteristics of an ca 1850 Disston. The actual configuration with the tapered blade does not appear on the Disstonian Institute saw profile page. The kerf is very thin. The saw is in excellent condition noting a sliver of one side of the tote tip and one spot of pitting 3/4" from the tip along the edge. 100% as found. Superb.
**All edge tools may need to be sharpened/honed before use**
