But you asked how to sharpen it didn't you??? The best thing to do is put it in a vise, blade up and at an angle that will allow you to easily run a file over the sharp edges of the teeth. You will notice that the blades are bent back and fourth, that is the set, you have to have a set in the blade or they will be pinched by th item you are cutting and that's a b---. There is a devise that sets that angle but for a hole saw it can be done by eye easy. Just make sure that they are all out far enough, that none are flush with the flat part of the blade. Then you need to take a fine file that is small enough to get into the grooves of the blade without touching the v at the bottom and changing it's shape. Notice the angle on the cutting edge and place your file on the tooth at the same angle and push it through, only touching the surface in between the teeth on the cutting edge. Keep the file flat on that surface all of the way through. Repeat this on all the teeth and you will have a sharp $5.00 saw that you just spent 2 hours on. Hope that helps...

With all due respect to James...he made a point...BUT I'll add my 2 cents as others have and might.
Consider for a moment the effort/ time/ energy involved in his very valid answer. Then consider; on a personal level, the value of your time and energy. I suspect they won't "balance"
We have lived in the age of Consumables for more than 100 years;and that relates to Tools, as well as anything else. Commonly known as "Planned Obsolescense" it is a fact of life, and our evolution.
I'd very much enjoy seeing a vehicle that was HONESTLY stated to last at least for the term of a warantee... IE:36 months, and then Nothing promised after...BUT have it sold to me at a reasonable price; such as $5000. Will that ever be more than a dream? Nope.
If I had a Nickle for every Dime I ever spent...or wasted, I'd have half as much.

It is so much easier to get another one instead. It would take a long time and a file to sharpen all the teeth. It wouldn't be cost effective to even try.
good luck.

I take mine to my saw sharpening guy. He uses a diamond grinding stone to sharpen them and for $3.00 it doesn't pay for me to mess with. If you are in a pinch I have hit mine with a hammer enough to take it out of round and used it for quite awhile before sharpening.

I use a Dremel with a cutoff wheel. Works fine and takes about 30 minutes.
