Hello Ultra,
here you can see a kind of compass Rotary cutter:
OLFA
in the attached photo, there are various pliers, knives (cut balsa) and glue, which I use.
If you are a beginner do not attempt complex models.
Rather you need to focus on very simple models in order to learn to use tools (scissors are fine too) and adhesives, and above all learn to fold paper (for this, follow the forum that is full of explicit photos).
In any case, do not give up, never give up!
If you fail, have patience and start of new line. You'll that in the end succeed.
Orazio
