severl oem manuals i have reccomend to sharpen the blade
,then file a 1/64 in flate on the edge.they claim it will hold this edge
much longer than a sharp edge.that sharp edge rounds off pretty
quick,but cuts good while its sharp. lucas
ds549 has it right. My Dad was a too; & die repairman and he told me to
do that many years ago and it works. I get by with about 1/2 as many
sharpenings and I am a nut on sharp tools, in fact I have a sharpening

I use a 4" angle grinder. It works pretty good for sharpening them. I
can't seem to get more than a couple of cuttings before they blades are all
beat to hell. I do have a few sticks and things in my yard, but no sandy
soil. I don't know why my blades get dull so quickly.
While we are on the subject, can someone try to describe the entire process
for sharpening a mower blade?
When I get a new blade, I know what it looks like, but I don't know the
correct "approach" to get it sharp.
I use a small bench grinder, and I hold the blade up to the grinder, but
usually I feel that I am grinding off more blade than I need. It seems
that knowing the correct "angle" to hold the blade to the stone is the key,
but for the life of me I can't seem to get the hang of it.
And no, this is not a troll.
These are the easiest tools to use, And with a little practice will b
sharpening blades like a pro, But don't foreget to blunt the edge
little with a flat file as mentioned above.
take a new lawnmower blade... it is usually painted black. Take your
grinder or file and grind the edge so that the paint is filed off
evenly. The new shiney edge should be even and straight exactly at the
same angle of the blade edge.
So on an old used lawnmower blade you will make the new shiney edge even
bench grinders with round wheels is a bit more difficult unless you can
master holding the blade at the precise angle everytime...
I dont have a bench grinder so I use a sharpening stone specifically
made for sharpening lawnmower blades that fit into drill motors/
Also I have an attachment for Dremel tools that are specifially made for
sharpening lawnmower blades. The Dremel attachment isn't quite as good
since it is hard to menuver the attachment around the part of the
lawnmower blade which is bent up for air deflection.
I nice new flat file would be the better way to go if you have the time.
