Sears still carries the replacement blades for the 23320!
I just ordered through Sears on the net.(took 3 days to get them!) The original part number was 18112 (at $1.75 in 1945 or so) $24.99 for a set of 3 plus shipping ($6?)
Sears shows then as part number 2293. They say they are "Inter Knives" whatever that means. The direstions for installing are different from installing on the 23320.

I found a parts list on the net. Can't locate now. But it's there! Along with the original instructions.
