How does one sharpen the blades and how often. How to avoid the rust on blades on brand new mower?

I haven't had to sharpen the blades yet, so I can't answer that part. I spray a silicone lubricant after every time I use the mower to prevent corrosion. The blades have stayed quite sharp, and you can adjust them if they ever have a larger spacing - I don't know if this is considered 'sharpening' though.

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.

Our knife blades are made from a high- carbon 420 stainless steel, however, stainless steel is not stain or rust proof. Please do not allow blades to soak in water, and do not allow acidic or salty foods to remain on the blades after use. This might cause staining to occur. Should the blade show some signs of staining, use a non-abrasive metal polish for easy removal. We recommend that you hand wash all knives thoroughly in hot water using a mild soap or detergent. Rinse in clean, hot water and towel dry immediately. Automatic dishwashers are not recommended as the heat and detergent can damage or stain the blades.

I just use it not getting it wet or anything . I think water might rust the blades

from RD: I have used the chainsaw sharpener...which worked fine, but haven't tried with the lawn mower blade sharpener as yet.

I have two of these. One is approximately 12 years and the other, maybe a year or so. Blades have never rusted. You need to maintain them correctly, which is simple - start here... http://www.osterstyle.com/service-%26-support/product-support/product-faqs/blades/blades.html (FYI, the blade on the Finisher is attached with screws. Get an appropriate screwdriver and remove to put new blade in place.)

My Mother has had these knives for a couple years, always put them through the dishwasher, and they're just as sharp (or, at least, not noticeably dull) as the day they were first purchased. I have yet to see them rust either. Hope that helps!

I can't answer your first question, but I can answer the second. I haven't had any trouble with my blades rusting. They appear to be stainless steel.

Once you get it sharpened you might try using a honing steel after each use. A couple of swipes and the knife stays very sharp.It will postpone having to have the knife resharpened.

Carbon steel is easy to keep sharp but it will rust very easily. Even wiping a blade with a paper towel leaves a little moisture behind. Coating the blade with just a tiny amount of food grade mineral oil can help prevent rust.

Carbon steel can rust, esp. the edge. Clean and dry after use and protect blade with Sentry Tuff cloth or any good rust protectant you like.

John Irvinejohn@gardenacanada.comBe sure to ask about how to sharpen the blades. After 1 season the blades were dulled and I'm not sure how to sharpen them.Gardena Canada Ltd.Member of the Husqvarna Group100 Summerlea RoadBrampton, ON. L6T 4X3Phone: 905 792-9330Fax: 905 792-8996

I have run mine through the dishwasher a dozen or so times. No sign of rust what-so-ever! I do not put my knives in the dishwasher, but found this has too many blades (that are very sharp) to safely wash by hand and get it thoroughly clean.

I would not be concerned about the razor rusting. I would advise getting high quality blades such as persona so the blade does not rust. The blades are available online at Amazon or at Sally's.

I use a lift to raise the front of the mower to a convenient height, then use a 4-1/2" angle grinder to sharpen the blades on the machine. Be sure to wear good gloves and eye protection, and remove the spark plug wires to prevent accidental starting when turning the blades by hand. With a steady hand, the grinder will do a sufficient job and you won't need to hone the blades afterward.

To prevent rusting before putting the blade away make sure it is clean and dry and you should be alright.

You cannot sharpen the blades - this is why this is a $40 tool and not a $240 tool.However I've had mine for something like 4 or 5 years now, I use it regularly, and it is still super scary sharp. So ... you probably won't ever need to sharpen it in normal household use.
