The chipping knives should be sharpened every 6-8 hours of chipping time. The knives should only be sharpened from the angle side of the blade. The best way is to use a slow speed horizontal bench grinder.

Patriot manual recommends changing the blades when there is 1/8" steel at the holes.

A good method is to cut the wood, wait a few days for some drying, and then cut/munch material. The harder/denser the wood, the more frequent sharpening. Also, try to avoid any dirt, stones, metal, etc. I have found the cutting blades to be quite durable, and most importantly on this machine design easily removable for sharpening. It is hard to give a specific period.

The blades as stated in the owners manual should have a "pulling action" bringing the materials into the machine. You will notice the difference in the feed because there will be more "pushing" involved. The machine will continue to operate and chip the material well after the blades are beyond optimum sharpness. I recall that I let my first blades with the factory edge go a long time. It's a great machine (I've had mine like 20 years and you won't find a chipper easier to store.) Note: even though blades will continue to "do the job" when not ideally sharp, as with any tool it is good not to let them go to the point where the blades begin to deteriorate. Inspection is very easy. All you have to do is remove the feed cone (3 1/2 inch nuts) and rotate the rotor and the blades are right there to view and feel the edge. You don't want chips to start in the blade. If you do keep up with it you can do the job with a sharpening stone as opposed to the expense and bother of a wheel, or having them done professionally. Hope this was helpful.

We enjoy the clippers but have not used them enough to have to have the blades sharpened yet. I can tell you experience with knives as well as commercial paper cutters that any blade will wear down when sharpened...At some point they will have to be replaced. Make sure that you use the oil when you use the clippers as this will help them stay sharper longer. Take care, Greg

It depends on how much of the edge is gone. If they can be rehoned it would require special sharpening materials and considerable experience. I would recommend replacing them.

If youre only grooming one dog or your own dog it will last a forever, oil the blade and take it to get sharpened when It gets dull cost like 5$. But if ur a groomer doing mass amounts of dogs it can last maybe 1 or 2 years. This is if ur purchasing a good quality blade as well

I don't know. I haven't had to sharpen or replace blade yet. It looks like it's just 2 standard razor blades. I was assuming you just replace when it gets dull.

never had need to sharpen them; but, if necessary, they should sharpen nicely. No, the warranty, as far as I know, does not cover replacement if they get dull. They probably have recommendations for keeping sharp, or best tool to use. Kershaw makes good knives and scissors. We've used for years and never had a complaint.

Mine came ready to go. I've used them numerous time and they still don't need sharpening. I've had them looked at by the experts at the rink and mine still don't need sharpening, but it depends on how often you skate. I just love these skates and you can't beat the deal. Hope this helped.

I'm not sure since I haven't had that issue so far. Have you tried to take them to a local hardware store to see if they can be sharpened? Sorry I wasn't able to help you.

if youre just cutting your own hair Id get a new blade every year. If youre a barber every three to four months months in my opinion. Just clean them thoroughly with cool care twice a week and oil them after every use and they last.

They are really sharp to start out with and they last a pretty long while. I'm not sure if they can be sharpened, although if they can't be sharpened I'm sure anyone could just replace the blades on then with new ones. I love these knives. Hope that helped in some way or another.

They last a very long time. Sharpening your knife before every use takes only a moment. I have never seen a sharpening steel wear out.

I have a cheap hair dryer that I use to dry the blades well after each shave. That Cuts reduces oxidation and my blades usually last three or four weeks.

Sharpeners work OK, but i prefer replacing the blades with new ones. Turning the blade over has no effect in my opinion. They last a long time.

Metal blades, with use, get dull. Fact of life. A loss of sharpness is not an indication of a defect that justifies replacement.

I don't think it needs to be sharpened for a very long time. At the price, you can always get another one. If you want to spend $130.00 and up, you may have to have it sharpened professionally .

The blades can't be sharpened, but some sharpeners can replace the cutter for much cheaper than the replacement cost of the whole blade. I send mine to Northern Tails Sharpening, he charges $10 to refurbish 5-in-1 blades.
