   Different sources, different products. Check with http://www.cggschmidt.com  http://www.ridgecarbidetool.com  http://www.globaltooling.com  and others at http://www.woodcentral.com/links/tooling.shtml

   You sure you need carbide?  Unless going with a spiral head, HSS is the choice of commercial shops unless doing teak or epoxy glue ups. If you go with carbide get the carbide brazed to a steel backer. Carbide is very brittle and the knife wiill shatter it it hits metal or an imbedded stone.

   I would go with the Byrd Shelix for the DJ-20.  The cutters are carbide and it cuts like a dream.  The change is fairly easy and you will never have to mess with changing those darn jointer blades again.  I have 5 years on one edge and I have three left to rotate to.  I agree with the others about carbide jointer knives.  Why?  If you are looking for less noise, more power, smoother finish and no tear out on figured woods I would change to a Byrd.  I did.  Now it is a better machine then it was when it was brand new.
