While I don't have near the experience with knifemaking and stabilized woods Darrin has, I agree with him 100%. K&G does a GREAT job of stabilizing, and it seems like they can do almost any wood.
Viral, I've done spalted pecan and a couple other spalted woods. It's not the spalted part, but the wood MUCH be very porous, which will make it very light (floats high in water). These do seem to stabilize good with Cactus Juice. I tried to do some Black Walnut (good solid wood) but it didn't take up much resin at all (I know it's not true "resin", but that's just an easy way of saying it). I talked with Curtis of Cactus Juice and he says Cactus Juice does work very good with Black Walnut. I did a piece of leather, boy it worked GOOD!!! Really soaked the resin up and cured really good.
One of the guides I use for wood, if it sinks in fresh water, doesn't need stabilizing, if it floats in water after stabilizing, didn't stabilize properly. If it sinks after stabilizing, good job.
