New carpet installed. Now I need to cut the door

[space-time]

Thanks.

Carpet is installed, no way I rip it out. Our family, our house, our rules, LOL

Noted that I need a better blade. At least I got the right tool.

Noted that I need to use tape to prevent splinter. And I plan to sand the edges to apply a small chamfer.

Noted that I need a straight edge tool. Will shop at Amazon for something similar. No way I go to a Harbor Freight right now.

Already knew to take pins out, not way I unscrew the hinges.

Thanks folks!
