This is a remix of the "Felling Wedge" by Jay_Omega.
I liked the idea of a DIY felling wedge (since these get chewed up from use) and the ability to make different sizes.
Jay's wedge did not have teeth on both side of them, so I created this remix.

At 100%, they measure about 6" long and are 2" wide x 2" thick.
The transparent one in the foreground (resized for comparison) is 6" long x 4" wide x 2" thick
