Hey everyone! I made a knex bailsong (butterfly knife) to pratice tricks for when I get a real one, But I would like to figure out what mass it is so I can compare it to a real one. i dont have a ounce scale around here or dont know anybody that has one is there a place online where i can find the weights because i cant find any thing online
