Applewood covers alot of ground simply because of the number of various speices.
My experience has been: (based on very limited use)
1: it is HARD...harder than sugar (hard) maple.
hard on edged tools! tends to burn easily if your not careful, but it does take an edge/profile beautifully
2: Prior to use, it has got to be dry, which takes a good bit of time when compared to some other domestics.
3: very susceptible to seasonal movement. More so than other domestics.
4: An excellent choice for tool use, ie. totes, plane body, saw handles, spoke shaves, mallets etc...
when it comes to furniture, turners like it, box makers, inlay and small decorative pieces
5: Spalting is not uncommon, in fact this IMHO adds excellent character to the wood. Can be kinda buggy/wormy.
Keep an eye out for punk wood as well.
I've only ever run across it in small privately owned mills/kilns. And always in smallish pieces and very limited quantities.
