Hello default and welcome to kit building.
I strongly agree with what chuckw and gboulton wrote, now that said I also made a list of tools needed for kit building, you can start building and acquire them as you go, I’m sure some of them you already have.

Kit building tools
===========
• Building board (must be straight and soft to pin)
• Roll of wax paper
• Metal rulers: 6”, 12”, 36”
• Razor blade saw (the one with the red handle, ZONA is recommended)
• Hobby knife with #11 blades
• Tweezers
• Set of files - round, rectangular
• Sanding block 11” and 80, 150 grit rolls
• Masking tape
• Clamps: small to medium of any shape and form as many as possible, you cannot have too many of them.
• T-pins – the smallest ones and cushion for pins
• Wing rib alignment Jig (the orange thing)
• Hand drill bits (better then using a power drill!!!)
• Rubber bands
• 12” or 18" quick grips for joining wing halves
• 90* deg triangle
• Long nose pliers
• Standard and metric hex wrenches
• Hobby syringe for aliphatic glue
• Clevis tool
• Epoxy mixing popsicle sticks, epoxy brushes and mixing cups
• Sealing iron (covering)
• Heat gun
• Soldering iron
• Pocket thermometer
• Single edge razor blades
• Slot hinging machine

These are the most important and most used tools, i didn’t get it all at once but with time.
