No. The unique wedge design of the Kindling Cracker means the blade does not need to be razor sharp to work.
It is easy to sharpen the blade, and some owners decide to do that. If you're an owner who likes to keep their tools fresh, this is how you maintain it:
1. Lay your Kindling Cracker flat and give it a few strokes with a metal file.
2. Keep it covered during rainfall, or keep it inside.
3. If left in the rain by accident, only the paint will be affected. Simply repaint, and it'll be back to normal before you know it.
And that's it. Easy.
