I'm pretty sure the OP knife is Maple due to the lighter wood showing thru the finish. Burl wood (knot wood) is very dense, and does not take penetrating stain(s) well. It does take surface finishes beautifully tho.
Not to be argumentative Ken, but it really depends on the type of tree the burl came from; for example maple and cedar burl usually absorb stains and dyes very well, until they are stabilized.
Most of the burl wood you buy that is sold specifically for knife handles has been stabilized. Stabilizing helps keep it from cracking and splitting and it also makes it much denser (in the case of maple). The stabilizing process usually makes finishing the wood much easier because it fills minute pores and often all you need to do is buff the stabilized wood with a fine compound to achieve a beautiful finish.
One burl wood seller says that maple burl generally doubles in weight when it is stabilized because of the amount of polymer it absorbs. Other woods like desert ironwood and cocobolo absorb very little of the stabilizing medium due to the density of the wood.
The stabilizing process increases the weight of the wood and also seals the pores of the wood so that stain and dyes do not penetrate it well. However, the stabilizing material can be colored and the wood can be dyed prior to stabilization. I have seen some truly spectacular burls with multicolored dye jobs.
