All About Pocket Knives

Evening everyone. Hope you all have been well.
I have a question.
I know that Buck made the 301(Schrade made) with grooved bolsters. I also know that some of them had all three tangs stamped. With Buck, Made in U,S,A< on the master bald and Buck on the other two.
I was wondering if they ever made the 303 or any other of the 3o series with grooved bolsters.
Thanks

The 301 and the 303 both started as Schrade contract knives, but the 301 was the only one with grooved bolsters. That version, along with a version without grooved bolsters and with only the master blade stamped, was produced 1966-1967. A third version with the secondary blades stamped "BUCK" was produced from 1967-1971. None of the Schrade contract knives had a stamped model number. In 1971 Camillus took over production of both the 301 and 303.
