Chris,
I just finished 4 small blades using stabilized redwood. I found the burled areas to be quiet a bit harder than the lighter wood. That burr will tend to dig into the softer areas , maybe. I have found a few checks inside that were not apparent
on the outside of block. Stabilized wood is a joy to sand and only needs a coat of wax if you take it to 1200 or so. I use red malle' which has more burl than the redwood and is more intricate. Available from; Arizona Silhouette, Bill & Kathy Baumbeck.
