Should I sharpen my blades "knife sharp" or should they have a blunt cutting
edge? Which is better?

They should be sharpened on the same angle as when new, to a sharp
edge. They don't need to be "knife sharp".

Nope. You'll take off too much steel. Just an edge.

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

Take a look at a brand new blade. They're not at all sharp. Also,
most of the cutting gets done by the outter corner of the blade.
That's moving fastest and crosses most grass.

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
service.

Man someone is making money with their sharpening service. I charge $3 a
blade. If it is off the mower. $5 if I have to take it off.

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.

It could be the blades. I sharpened a set that came on a Sears tractor
that was soft. You could bend them with your hands.

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.

Stick it in a vise and use cheap mill files to make it similar
to the way it was new. A grinder would be much easier, but it's
not all that bad. daveA

I already have a grinder, and a vise. What I am asking for is the
technique.

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/
cordless drills.

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.

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
and straight.
