Sharpen blade: buy tool or pay?

Are there inexpensive tools to make sharpening lawn mower blades easier? I've seen a few at hardware stores but I don't know how effective they are. I'm not willing to spend the money on a grinder so am I better off paying to have it sharpened?

I'm not recommending anything other than grinders, you might dull the blade more than sharpening it with other tools. Get a DIE GRINDER, they are cheap, and can do the work, I've seen them for as low as $10, thats probably as much as you'll spend on those "inexpensive tools"

You can buy an angle grinder relatively cheap [lower end Black & Decker or some other off-brand and not a Dewalt, Bosch, or Makita...get into those three and your prices will increase] and sharpen blades yourself. I have a Dewalt 28402 4 1/2" angle grinder that I use a 60 grit flap wheel on to grind my blades. For years I've toiled away on a bench grinder but those things are really slow compared to an angle grinder. The only way you can take out dings in the cutting edge of a mower blade is to use a grinder of some sort.

I don't typically like to buy single use tool but if I can find it for under $20 I won't mind it as much. Would a Dremel work? I don't own one but I've been looking for a reason to buy one.

I have owned and worn out several Dremel tools. Personally I do not think that they are up to this task. They are just not large enough and lack power to do the job in a reasonable length of time. The stones are not large enough to have a decent linear speed.

That said if you take enough time and go slow it will do the job. Personally I use a bench grinder. Other good choices are belt sanders ( mounted so you can hold blade, not sander) or the rigs that use like a 36" x 1" belt ( I have used one and it does a good job) . I have not tried a n angle(hand held) grinder but I can see where it would be fast.

I use a cheap chinese angle grinder (cost me around $12) and put a high quality wheel on it to sharpen my bushhog and mower blades. Takes around 30 sec or so per edge. Don't sharpen them razor sharp and the cutting edge lasts a lot longer.

Dremel would take probably 15 min per blade at the fastest and I'd go through a couple of grinding wheels per blade.

If you get a big nick, take the blade off to sharpen it and check the balance.

The grinding wheels with an angle guide that you put in your drill may work but they're so slow it's painful.
