Are these blades sharpened from the factory or do they have to be sharpened

The Blades are sharpened from the Factory. An annual sharpening is needed by the Honda and other rotary Lawn Mowers in typical usage. A few rocks, some pieces of wood and the occasional child's toy cause nicks and dulling of the dual blade cutting edges. Perhaps more important is the need to keep the underside of the mower clean. Mowing in wet grass is particularly quick to accumulate "stuff" in the underside area. Follow the instructions in the Honda maintenance literature that comes with the mower to do the cleaning safely. I found the Honda mower engine one of the best for easy starting and smooth running! Good Luck! The Blades are sharpened from the Factory.

Very sharp and stay sharp! Yes they can be sharpened using standard method for sharpening or take to a sharpener. How often will depend on usage. When I reviewed these knives they were rated very high. I hope this helps with your decision to buy.

The blades are removable but should simply be replaced and not sharpened.. I cannot imagine, with reasonable care, that you would need to sharpen the blades.....

Just bolt them on as is. They do a great job. I just sharpened mine after two years of mowing 3 acres a week. These are the best!

The ones I got were sharp. Actually used last 1/2 of season without having to sharpen. They appear to hold the edge pretty good.

I have two sets. The first set I bought 2 years ago and the second set last year. I have never sharpened them. I love these knives.

The blade is approximately 10 - 15 degrees from the handle's axis. These knives should be able to be sharpened with any standard sharpener, although due to the quality of the steel it is exceedingly unlikely that they would require sharpening before 10 or so years of regular use.

I have not had a need to sharpen the blade. It has been used seasonally and this is the second year of use. It is extremely sharp when it arrives and it remains sharp. I'm not certain as to what I will use to sharpen when the time comes.

They get gradually duller. Depends on how long you can tolerate to take to shave (and touch up with a blade) before replacing. I was on the same blades for 5 years or so and realized how bad they were when I forgot it on a trip to France and bought a new one there. You can supposedly also sharpen them a bit: http://www.youtube.com/watch?v=qSBX81U1otM

The Blades come Sharp, so be careful when you are working around them. I cover mine when not in use, because of my noise cats. They are not as sharp as knives, but I would Still be careful. I would Think once a season would be a good time to sharpen. There is a kit that you can buy for that.

they are pretty sharp...i did take a flap disk sander wheel on a grinder to mine just to knock the paint off...i was waiting for the oil to drain anyway ...these blades are much thicker and i'm sure they will last 2x as long as the factory blades

I don't think you can sharpen them, we ordered new ones from the manufacturer.

These are just double edge blades. You need a razor that takes a double edge blade.

We used them 4 years in a row and we never sharpened them. I just made sure to clean the blades after eavh use. Both boys loved them.

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 you read the description it says they are serrated. I don't think you can sharpen serrated blades.

Yes they can be sharpened in fact I run a few swipes on my fine steel between uses to keep a keen edge and haven't needed to really sharpen them yet.
