* Sharpness. Of course, any anchor can be sharpened. Sure that takes off the galvanizing, but if you anchor much, it doesn't seem to matter much. I've done this to some knockoffs and it helped a great deal. How much will depend on the anchor and how you sharpen it.
* Clog resistance. This includes both mud and weeds, which are different.
* Other stuff I've forgotten, like balance, fluke shape, and on and on. The usual stuff.
Something to consider is that while the fluke may penetrate, the shank and chain will probably be held on top of the root mat. Will it be like pealing sod? Clearly this depends on the depth of the roots. It also makes it sound like you should not sharpen too much of the fluke, only the very tip.
