Sorry if I got carried away with my 3 and 4 knife suggestions.  Maybe for another time if a 'set' is being built.  
I agree with the concerns about price which have been expressed, and so I am voting for "A".  
If, however, "B" wins the vote, I'm campaigning for a pair of Model 5-6's, one with sawteeth (Assuming that this is even still an available option for the Model 5.  I question this only because the Model 5 is not among the models listed for which sawteeth is an available option on the RMK 'Extra Features' website page.) and one with sawteeth/no sawteeth.  Assuming that the above would be sufficiently "matching" to be a qualifying matched pair?
