Do I need to sharpen these circular blades?

Both of these blades are flipping the overload switch.
Any chance someone can help me to figure out if these blades need sharpening?

Barry,
do either of those blades feel almost cut your fingers sharp?

If not, the blades will need sharpening.

But as others have said, at their price point, the cost of resharpening a DeWalt blade is very close to, if not greater than, the cost of a new blade

Nope. Plug Boss it's not.
No difference.
Plug Boss safety switch fired.
Bummer.


Oh and sharpening:
Tungston
16 tooth - $20
100 tooth- $42.50

Is there a way I can sharpen them myself?
Is it worth the time?

Well that's interesting.
30%(?) more material to cut thru.

The tooth just above the work piece is for safety without a blade guard.

This full height is for pulling the work piece down instead of out.

Is there a way I can sharpen them [Tungsten Carbide Teeth] myself?
Is it worth the time?

Barry, it can be done
BUT
you will need two (ultra coarse and fine), or possibly four (ultra coarse, medium, fine, ultra fine) diamond hones.
Then you will need an accurate jig to hold the hones at the correct angle,
Then you will need to ensure you remove the same amount of carbide from each tooth -- you don't want to unbalance the blade


to my mind far easier to either to pay a professional to do it for you.
