To sharpen them secure in a table vise. Now attach the blade sharpener to the end of your power drill. Make sure to wear eye protection and work gloves.

Top 5 Lawn Mowers recommends the Sun Joe MJ401E to people with a small yard who dont want to spend a lot on a mower. The reviewer liked it overall for many of the same reason one might like any electric mower (no fossil fuels lightweight etc.) but he also noted that there were only three height positions with the lowest scraping the ground. And due to its 14-inch blade it takes longer to mow a lawn.
Consumer Reports recommends the Toro Recycler 20333 because of its very good ratings in ease of use handling side discharging and bagging and excellent mulching. The reviewer specifically liked the washout port for cleaning buildup under the sizable deck. The Wirecutter used to list the 20333 as the runner-up pick but supplanted it with the 20340 because of the newer models upright storage. However the reviewer still recommends the 20333 if the blade brake clutch is more important to you than compact storage.
