Here are a few Redwood burl knife handle blocks and scales.  

R152, $15.00  Redwood burl block measures 1 x 1 5/8 x 5 1/4" long.   Very hard burl.....the kind that "klinks" instead of "clunks" when you tap it on another piece of wood.  You burl guys know what I mean.  This one has some very small pits in it, easily taken care of with just a drop or two of CA.   Would make good knife handles or scales.   

R154, $15.00.  Redwood pin burl block, measures 1 x 1 1/2 x 5 1/4" long.   Really special piece of old growth burl, very hard, came from the same larger piece as R152 above. 

R226, 12.50.  Redwood burl block, could make a very nice knife handle.   Hard old growth type wood.  Measures 15/16 x 1 5/8 x 5 1/4" long.
