This blank is part of the popular "Matrix" style blanks that we've been selling for years at Bear Tooth Woods. This matrix blank has various shades of red and purple.
On these blanks, two sides are fairly even; but the other two sides are "rough." This is due to how it was constructed. To keep the cost down, they did not clean up the two sides opposite the corner where the layers were aligned. These blanks are being sold as seconds as there may be some voids between the layers where the layers were not fully glued together. This can often be corrected with some CA glue to fill in those voids, but the voids should be expected and this is why the blanks are being sold at a discount as seconds.
