#1 Are my Knives worth sharpening?

If you use them, then yes, they are worth sharpening. Your knife does not have to be expensive to feel good in your hand. Remember a sharp knife is safer than a dull knife.

#2. How often should I sharpen my knives?

That will vary. It depends on the quality of the knife, how the knife is being used, what you are cutting, and what you are cutting on. Proper care will prolong the edge. Do not cut on glass cutting boards or granite counter tops. Do use wood or soft plastic boards, do not put into a dishwasher and Do properly steel the edge. Steeling will not sharpen a knife, it realigns and maintains the edge. Eventually the edge "falls off" then it is time to have sharpened. This might be needed every 6 months or once a year.

#3. What equipment do I use to sharpen your knives?

Its a secret :) not really. I use a series of one inch belts of very fine grit on a sander to establish a primary bevel, I move to a silicone carbide grit paper wheel to define the secondary bevel, I then move to a slotted paper wheel loaded with white compound to remove burrs and the final polish is on a compound loaded leather wheel.
