Well Koto is very pretty and very distinctive cut across the grain, you can't miss that. Limba kinda of shines on the length wise end of the grain and has little holes when it's cut across the grain, it looks a different colour depending if you are looking down the length or across the grain. The Ayous core's have holes on the length grain and Paulownia (Kiri) kind of has bumps and shows up saw marks really easily. Walnut is brown, can't miss that. Spruce has distinctive lines in the grain. When I got home from my holiday maybe someone can remind me to take some macro pictures showing the different wood in blades and how to spot them.

Hello everyone, I'm brand new to the forum but have been referencing it for a while now. Just thought i would share with you in this thread and add another type of wood. I am currently building 2 blades with a "Butternut" core. Here's the details:

Butternut: Slightly Heavier, Harder and less elastic than Balsa. Fairly inexpensive. Like Balsa it is commonly used as a carving wood. Has been known to have tear out issues if taking too much material off at once, however using sharp blades and finer sandpapers I have yet to experience any tear out. (will update with playing tendencies soon).

Common Name(s): Butternut, White Walnut

Scientific Name: Juglans cinerea

Distribution: Eastern United States

Average Dried Weight: 27 lbs/ft3 (435 kg/m3)

Janka Hardness: 490 lbf (2,180 N)

Modulus of Rupture: 8,100 lbf/in2 (55.9 MPa)

Elastic Modulus: 1,180,000 lbf/in2 (8.14 GPa)

Crushing Strength: 5,110 lbf/in2 (35.2 MPa)

Color/Appearance: Heartwood is usually a light to medium tan, sometimes with a reddish tint. Growth rings are darker and form fairly distinct grain patterns. Sapwood is a pale yellowish white.

Grain/Texture: Grain is typically straight, with a medium to coarse texture. Silky natural luster.

Pricing/Availability: Available as lumber and carving blanks. Prices are in the mid range for a domestic hardwood.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species. However, many Butternut trees in North America are currently afflicted by a fungal disease (Sirococcus clavigigenti-juglandacearum) known as Butternut canker. The rapid decline of Butternut has prompted the US Fish and Wildlife Service to list it as a species of federal concern. The tree is protected in Canada as well.
