Thanks for the vid! (I haven't watched the whole thing yet though.. a few mins to go)
I made another(smaller) point and a blade-like object. Pics up soon.. once I find the camera!
Thanks for the biology(?) advice... have tried cutting leaf samples with glass scapels(super thin flakes mounted onto a wooden haft) and it makes it easy to see stuff.
BTW humans don't have cell walls, we have cell membranes
