its to broken apart D: and honestly, you could do this with much less in the vertice department, nice texturing though (darken handle), you should use my chain concept, Rectangular plains 1.5/1 (Height to Length) in 90 degree pattern. 1 Length = 4 Vertices, so rapping that model would add only about 80 o.o.
First Step Of Chain (Create all your plains with extrude)

Second Step of Chain (Move one the sides of the chains up 1/2 of the units you used to extrude, then bend the chain)
