What can I say but... Wow!  An extremely rare find at times.
 
Mexican Kingwood has by far some of the most unique grains and colors I have seen for knife scales.  What you are seeing here is not dyed but it's natural colors and grains.  The heartwood is a dark purplish or reddish brown with darker black streaks. Sapwood is a pale yellow.  Reported as being very durable in decay resistance, and is also resistance to termites.  It's rating hits the Janka scale over 3,300 lbf... That's a hardwood!
 
The photo's here are exactly what your getting.  I only have these pieces and I'm not sure when I'll get more.  
 
NOTE: There is only one of each and it is a first-come-first-serve basis.  I do my best to track inventory but if an item is sold out I will notify you and we can find a replacement or I can refund your purchase.
