now that i have this knife holder mounted, i'm very pleased with it.  but getting it there was more difficult than it should have been.  I had to make my own template.  we're talking about one piece of paper that would have been very easy for the manufacture to supply & more accurate than mine.  next, drilling the holes.  again, the manufacturer could have said what size bit to use but failed to do so.  and now i am sorry, as i have lost my notes and don't have it either.  once up it holds a lot of knives and keeps my workspace clear, also it's very handsome!
