+1 for scibeer. He has been recently modding Farmers by adding scissors, as well as the magnifier/Phillips layer. I have not seen him do a Cadet, but it may be possible, given you can find a donor knife for 84mm frame scissors (could be a problem).
Of course, there is an original vintage Vic model with scissors being sold on eBay right now, but you will probably not be able to afford it, I know I can't!

P.S. I am assuming you are looking for something larger than a Classic or a MoneyClip - those are widely available in Alox...
