There are some new knives on the market called "ceramic knives" that are made out of zirconium (the same stuff as fake diamonds.) They don't get dull because they are are wear resistant and should stay sharp for life. Be advised that ceramic knives are very expensive!
Right before Thanksgiving I took my set of knives to be sharpened at Westpfal Henry in midtown. Here is their wesite: http://www.nysharpeningservice.com/ They did a great job and I had smooth cutting for all my holiday prep!
These days we can see that the artificial stones
match in quality to natural stones and sometimes even better in sharpening
performance due to consistency of particle size and control over the properties
of the stones. When artificial stones gradually entered the market and were of
good quality. Mines of Natural stone where closed and that caused the prices
for natural stone to go higher. These days, getting quality natural stone is an
Every time you use your knife, the edge will become
slightly less sharp, and you are more likely to injure yourself with a dull
blade than a sharp one, as they can slip while you are working. Make sure you
buy good knife-sharpening steel and use it each time before cutting with your knife
it will also prolong your knife.
You can sharpen your
Swiss Army Knife is using a circular motion. Start by holding the blade
away from you at the proper angle. Run the blade of your Swiss Army Knife in a
clockwise motion on the stone until you have sharpened that side of the blade.
Turn the blade over and repeat with a counter clockwise motion.
The knives could be dull, you would have to be the judge of that. If the bevel & face are rusty they are probably dull. They can be honed or taken to a sharpening shop.
The outfeed table could also be too high. I usually adjust the knives above the outfeed table. I use an aluminum straight edge & adjust them using a sheet of printer paper on the outfeed table so that they are about the thickness of the paper above the table. I place the paper on the outfeed table put the straightedge on the paper & rotate & adjust each knife so they just slightly hit the straightedge when I rotate the cutterhead by hand. Needless to say the jointer needs to be unplugged while doing this.
The board could also be convex to start with. To fix that problerm start jointing at the start of the convex part and not at the end of the board.
Maintenance (excluding the power plant) Your primary maintenance concern with chippers and shredders is their knives. You can re-sharpen chipper knives, whereas you can reverse shredder flail-type knives when dull but you can not re-sharpen them.
You must sharpen chipper knives with special sharpening equipment because they are made of high-carbon steel. Maintaining sharp knives can lengthen their life and the life of the machine by keeping power requirements low. An over-dulled or chipped chipper knife will need extensive sharpening, which will remove a large portion of the blade. This obviously will shorten its life. As soon as a blade is slightly dull, you should sharpen it to minimize the amount of blade-material that you remove. All knives need sharpening at the same time to keep them in balance-even if only one is worn or chipped. Also, you must use matched sets to keep the knife the same distance from the anvil for proper chipping and feeding. After removing the knives, clean the area where they are fastened with a wire brush to make sure they will align correctly. Be sure to torque the knife bolts to their proper specifications. You will need to examine the anvil and be sure it maintains a good, square edge. Occasionally, you may need to remove and sharpen it.
