This Wood is NFG

[69_knives]

Stopped at my favorite wood shop today and found this 20x6x1.125" piece that somebody had marked "NFG"...

Looks pretty good to me!

I don't know the name for the iridescent white lines but I think they look pretty cool. They're skinnier and tighter on one side and it was harder to take a pic of the nice iridescence but I tried in the second pic.

Looks like quartersawn oak. The ray flakes are the tree's medullary rays that transmit sap radially through the tree. They show up when the wood is cut radially.

The ziricote on the upper knife shows a similar pattern of ray flakes (and so does the sycamore in the background). This effect is seen with many species of timber, but is unusually prominent on woods like oak.

That is indeed what it is.

Medullary rays. Gotcha, I learned something today. That and that oak can be cool too!

I think most wood should be quartersawn as it greatly reduces the movement of the wood (plus it often looks cooler), but you get much less quartersawn wood out of a log than rift sawn wood.

For anyone who doesnt know, wood expands along it's width in a normally cut board. Because the board is fairly wide that causes alot of expansion. However if the board was quartersawn what would normally be the width becomes the thinkness instead, and because the board is relatively thin you get very little expansion and contraction.

What a great board i wish all the oak I bought looked like that, tell them to st aside more NFG boards like that for you.
Cheers Ron.

I don't know. Good flat-cut cocobolo can be amazing. Same goes for many other species. Sure, the 1/4-sawn stuff is better structurally, but sometimes tangent faces look amazing. (I would take quarter over rift almost every time.)

p.s. All oak should be quartersawn.

Here is a guide to show different cuts on a log.

While that diagram does show how lumber is cut on an industrial scale, those cuts would not satisfy many of the "wood junkies" here.

For example: The diagram for quartersawing would yield very few truly quartersawn boards. A truly quartersawn face is perfectly perpendicular to the annular rings. If they cut high-quality lumber like that, and sold it all as quartersawn, they would get much of it returned (and not get returning customers).
