I have many old dull Norelco rotary shavers in my bathroom drawer, that the blades cost almost as much as a new shaver. I decided to try to recycle them by sharpening the blades. I looked on the internet and found some gadgets and some articles about how to re-sharpen the blades. One said use a piece of glass and lap with tooth paste, the gadget was a abrasive cup that you put on the shaver and run the shaver. On one shaver I did the glass lapping, it was tedious, however it worked fine. On the second shaver I tried a different procedure that was easy and effective, here is what I did. Carefully removed the heads with blades from the shaver, keeping the blades with the original heads.
Cleaned the shaver with a small brush and each blade/head with water and brush, keeping the paired head/blade assembly.
I then took tooth paste and put a dab (1/4inch long as it comes out of the tube) in each head and installed the mated blade on top of it, re-installed them into the shavers head holder. From the back of the head holder I added 2 drops of water to each tooth paste dab.
Holding the shaving surface down so the water and tooth paste wouldn't run back into the shaver, I carefully closed the head holder, and ran the shaver for about 20 seconds in the shaving surface down position.
Keeping the shaver in that position I removed the head assemblies and cleaned the mated blade assemblies and their holder by running under the water tap. Dried all the parts with a towel and blowing out with my mouth, then re-assembled the shaver. I have had several shaves with it and it performs like new.
