Description

Our cut and ground preforms are different than anyone else's. (At least that we know of) Our cut and ground preforms are rounded on either side and thinned out, making pressure flaking and knapping faster, and much easier with a more exact shape! Our "preshaped" items are only shaped into a point on either side. It is still thick like a slab, but still very useful in the knapping world!


Flag Glass Preforms
These are ground in the same way as our other preforms, and are designed to finish with just one pass. A great time saver they measure approximately 1 7/8" wide by 6 1/8" in length.
