Tools to Remove 27" LCD/Screen

I am trying to find the kit with the removal wheel tool and the adhesive strips. It appears that iFixit has the market cornered on this and is OUT OF STOCK. There is also a card they sell as well. Looks like a credit card to me.

Per their guide this is what you need to remove and re-install a new LCD/Screen on the 2012 iMac's. Does anyone know of anything else I can use in place of the little wheel tool. You run it down between the glass and it cuts the double-stick adhesive in half to allow you to lift out the LCD/Screen combo. I can get the double sided adhesive strips at Amazon. Is a razor blade advisable to do this? I wouldn't be jamming the entire blade in all the way.
