Finally took some photos of this one for this thread to share…
An unusual and rare to find Boys Knife were those designed as blunt safety knives .. This knife along with Joe's (FRJ) blunt safety knife from Northfield were together in one photo in the boys knife article a few years ago.. I am also posting a catalog cut at the end of the photos that Neal (Mason) kindly shared for a similar boys knife safety blade printed in 1900 though I am not sure of the company….
T Smith & Co / Cast Steel was a Sheffield firm and though Goins lists T Smith & Co from 1797-1800 but I think that may be incorrect. I’m guessing this knife was mid to later 1800s. Tweedale had a T Smith but he was only noted as a razor maker in the mid 19th century.
Knife is 2 & 7/8” with cocobolo handles, iron liners and threaded bolster. Though the end was blunted the knife was no doubt sharpened… Joe has a Northfield of the same exact safety design - size, blade shape, cocobolo wood etc

I believe both of these knives were in the collection of Tom Heitzman at one time.
