Another old catalog posted to archive.org (thanks to Mark Stansbury): https://archive.org/stream/VaughanFineTools1940/Vaughan Fine Tools 1940#page/n5/mode/2up Interesting that the Vaughan axes were made by electrically welding a "tool steel blade" to a poll/eye made of lower-grade steel. The single-bit axes started out as two pieces, and the double-bit axes were four pieces, before the welding. (see catalog page 5, archive page reference 7/32) The Vaughan "Sub-Zero" Axe has "no high-carbon steel in the eye to crystallize when frozen." It gets a special Double Heat Treatment after welding, and is said to be suitable for chopping at temperatures down to 50 degrees below zero (see catalog page 6, archive page reference 8/32). Vaughan had a "Tropical Hardwood Axe" having an "extra-thin" (with high-centerline) "Chip Clearance Blade" (see catalog page 7, archive page reference 9/32). More axes are on catalog pages 8 and 9 (archive page references 10/32 and 11/32). Some Vaughan hatchets appear later in the catalog.
