I was going to ask that question about sharpening. The box the blade
came in said to save it for shipping when getting the blade sharpened.
I'll likely do just that.

Forrest blades stay sharp for a long time. I would just leave the blade on
the saw until it needs to be sharpened. Then put your old DeWalt blade on
until you get the Forrest.

Don't make the mistake of sending the Forrest to anyone but Forrest for
resharpening...
