Handmade Wire Cutting Frame

With a little bit of basic math you can make your own.
25/2 = 12.5
12.5/2 = 6.25
From there just do a 1 inch cut to figure out how many inches you need for your preferred clay weight.

Clay straight out the bag does not need to be wedged unless small bits are added to achieve a desired weight. Most clay companies will sell blocks of clay that have been pugged and De-aired.
