I was sharpening a Type 16 Stanley #5 that I picked up a while back tonight. I use a Tormek which allows a very nice hollow grind. As I finished and got ready to flatten the back, I noticed that the iron was laminated. I couldn't believe my eyes as the blade was the standard Type 16 with the notched logo and Made in U.S.A underneath made starting in 1936. I confirmed my suspicion by testing on my Rockwell Hardness tester. The laminated side measured right at 60C. The back (bevel side) was mild steel. Very surprised to see laminated irons made this late. Recorded here for posterity.
