Larry, Joe, Tom - thanks for the compliments on my composite handled knives.
Larry, your 54's, 75's, and 91's put my little pile of 45's to shame.
Tom, the 45 SAB whittlers are very difficult to find. Your MOP is example is very nice
One of the reasons I like to collect 45's is because there is a large number of variations in the number blades, the handle materials, and the blade configurations.
I have shown my WR Case & Sons 8345 1/2 SAB before, but here it is again for comparison to the fine example that Tom posted. I believe mine might have been rehandled based on the collection it came from. Mine is also a contract knife based on the "Bradford Penna" stamping and I would like to believe it was made by Napanoch, although the 63045 Pliers knife with Bradford Penna stamping was made by Valley Forge. In addition to the Bradford Penna stamping it has an unusual pattern stamp on the back of the saber ground clip blade that says "8345 SABER". The clip blade shape and nail nick on Tom's example matches to the Tested XX 6345 1/2 SAB while the clip blade on my example looks more like a clip blade you would see on a 83SAB whittler.
Please let me know if I am posting too many pictures and blathering on too much. In case you couldn't tell I'm a bit (lol) of a nerd when studying these old knives.
