I picked up an interesting old case office knife from a gentleman on ebay, it is a CASE BRADFORD,PA. and was in as new unsharpened condition.
For US $35.00 it is a real steal and has taken a very good edge, point of fact I cannot see any difference between how it takes an edge and how the Case XX and Case USA do.
3 3/4" long with celluloid scales, with ever so slight shrinkage of the celluloid and slight peppering from the celluloid gassing off over the years.
I shall be taking it to work for opening boxes and such.
