This is some second growth redwood that just doesn't look normal. Kind of in between burl and flamed.
Part of that is because of cutting it quartersawn. Still the coloring and overall look are different from what you would normally expect to see with redwood. I like it but it is kind of different so I might be the only one.
I just got another shipment from being stabilized at K&G. These are the ones I started cleaning up first. Top left piece isn't redwood.
