Another try at plywood, again started with making a block of plywood, and carved away, ended up very different from what I thought it would look like, but just like life not everything goes as planned.
Anything that can be easily crumbled, crushed, broken, sheared off could be considered friable, and plywood because of it's multiple thin ply's fits that bill. Baltic Birch a little less so because so much care is made to fill voids with the donuts/footballs they use, but along an edge it can crack away from it's neighboring layer leaving large unsightly gashes. Even cutting it on a table saw is sometimes a chore to keep the edges clean. One of the main reasons track saws with their rubber edge lines are so popular. Going at it with a cutter head I would think it would make it more so.not 100% sure what you mean by 'friable edge'
