Subject:
Very likely Tungsten

Patrick Chase
Based on the active date range you give for the maker, the steel would almost have to be Tungsten based, i.e. T1 or one of its non-standardized forerunners. Molybdenum-based HSS didn't become common until WWII.

If it's actually branded as "High Speed Steel" then that dates it to the 20th Century.
