i am having a hard time understanding how you can cut the base trim without doing damage to the floor?
If you are installing flooring and need to undercut the door casing and trim, then you are probably working on top of the subfloor so damage isn't an issue. And I wish this tool existed when I installed our floor. I cut every single door casing by hand, laying on my side. That took just as long or longer to do than laying the entire floor itself. Not a fun job!
