Pear can be gorgeous. Google pear wood guitars, etc.. astounding looking, but that grain is weird, and I tried to rough out a pear stave once and it just didn't act right. The grain on the belly went everywhere, wiggled like small tight hairpin wiggles, and chipped out at strange angles when I tried drawknife or machete. It FEELS weird to work. I kinda gave up on it when some powder beetles got under the bark and i wasn't sure I could find a new ring. Made some knife handles, and a couple bow handles. Beautiful.
But the outside, the back under the bark, before the beetles, showed none of what the split surfaces did. Straight grain lines So I guess it should have held together. This was from an ornamental flowering pear.
Also once tried some fruit tree trimmings about 1.5" across just to mess with them, and they were very brittle when green, but the wood seemed so different from the log I described above.
