Mike,

I found a few mentions of sharpening. It looks like Centaur offers a 
sharpening for $65. Seems like enough!!

Sharpening Shear Blades: (missed that one). That depends on the type of 
shear. Long precision metal (paper and other) shears are normally 
sharpened on a surface grinder or with a precision sharpening fixture. 
This is the only way to produce an absolutely square straight grind. 
Often blades from large shears must be sent back to the factory to be 
sharpened.

  Short shear blades can also be sharpened on a belt grinder with a 
table set exactly square. Special shear blades like those for a Beverly 
Shear must be ground at a clearance angle. On the Beverly that is 10 
degrees. This angle must be very accurate as the blades pass each other 
at that angle. To do the job RIGHT requires a special fixture to hold 
the curved blades at the correct angle. And folks want to know why one 
gets pissed when someone chips their new Beverly Shear blades. . .

  After sharpening on a precision grinder the edges have any burr or 
wire edge removed by carefully stoning with a fine stone. When 
installed the blades are adjusted to have a minimum non-contact 
clearance. This is usualy only about .005" (.13mm) and is set using a 
feeler guage.

  BTW a flapdisk and a steady hand does a great job sharpening the 
blades as long as they're not to beat up. and keep an eye on the 
alignment to ensure burless cuts.
