My wooden back scratcher's fingers weren't meeting my high expectations of actually scratching my back. Imagine raking a piece of cardboard across a fierce back itch. Not very satisfying. I need something sharper. This is my solution which took about 5 minutes. Making the Instructable took considerably longer than the actual project! Enjoy.
Step 1: Gather Supplies
I used my existing back scratcher and a few tools.
Dremel cut off wheel
Dremel sanding band
I am not responsible for any injuries you get while following my instructions. Tools are dangerous.
Step 2: Cut the Fingers
Clamp the back scratcher to your work surface. I highly recommend using two hands when using your Dremel. Use the cutoff wheel to make the square fingers into points. I free handed this step. Don't worry if the fingers need some polishing up. That's next.
Step 3: Sand and Round Off the Fingers
Once cut, remove the cutoff wheel and install the sanding band. Now use the sander to smooth the surfaces and edges.
Step 4: Test the Scratcher
All backs are not created equal. You will now want to test out the sharpness and make sure that your back can handle the new fingers. If too sharp, use the sander to round off the fingers until they agree with your back.
Step 5: Enjoy
Store by your bed or wherever you do most of your back scratching. Enjoy!
