These are the 1x4 for WE prototypes, sending them to my beta tester today. We have Jende Whetstones, KME and CGSW stones for testing of the cleat. If anyone out there has other brands of 1x4 stones could you post a picture of the them. Most interested in the shape of the backing plate on the end and the thickness in of the backing plate. Color coding was requested so I put 2 small recess on the cleat end and will make the cleats white going forward so that a drop of paint can be applied by the customer so they can customize them to their taste.
