Step 1: Materials and Tools
They are very little :
1) Big file
2) Small file
3) Sandpaper ( not showed)
1) Soda can (can by Dr. Pepper , Pepsi , Coca cola , arizona is not soda but work , any of this tipe of can works ).
Step 2: Start With the File Work
Step 3: File Process
When this little mark start showing you will rotate the can to keep with file process.
Step 4: Finish With the Big File
When you note all the can have this mark you will make a little tap with file on the top this will fall and you need to take it off.
Step 5: Small File Process
Now with the small file eliminate the sharp edge (file in the top , side and outside).
