This is a basic metal comb.  It comes in 10" comb like the one you see me using in except this is just steel, not aluminum.  For aluminum, go to aluminum comb listing.  Once we are out of stock here, since Covid-19 has Andis Company closed, please order an aluminum one. If you want a lighter comb, please go order the aluminum one.  I use all of them.  But I use the aluminum version 99.9 % of the time!
