Aerolite Adjustable Wrench
This 6'' adjustable wrench is made entirely out of Gr5 titanium and only weighs a jaw dropping 57 grams!! It's unreal when you pick this wrench up, it feels so light compared to a steel version . The jaws of this wrench open all of the way up to 21mm.
This is a great addition to any toolkit. Weighs a fraction of the steel version and will not rust.
