Describe This

This object has two different parts that interlock to form one powerful object. The body of the object is narrow and cold like a flag pole in December. The body also shines like a diamond in the sun and has a green glow to it. The front part of the object or the "head" is strong like a the spine of a book but still has many holes in it. Through the wholes are many pieces of colorful string interwoven perfectly to form an almost spider web like appearance. See if you can guess what my object is.
