Now I have an antique plug cutter made of cast iron and a new blade made by Bingham Knifeworks. It cuts like butter.
It is fairly expensive and it takes time to cut the plugs and you tend to have inconsistent thicknesses of the flakes as a result.
Enter the cheapest meat slicer on Amazon!
What is nice is you get two blades. You can adjust the thickness of the cut. What you need to do is extend the holding tray right up the the blade. I used two box tops from cigar boxes.
You get nice consistent size flakes and it won't tear at the bottom. You can just about slice up the entire plug as seen above! The flakes come out perfect for a fold and stuff from a 200g plug.
