I am glad you found the info worthy Jack!

It is good to hear that my long-winded rambling isn't always skipped over and is sometimes found worthwhile.

brb still reading KnifeGuy's last post....

so you'll get back to us, what, tomorrow? <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />&#9824;

actually from what i've seen compared to some other knives sr77 will chop/tear easier(but still under extreme extreme abuse) than some knives, but unlike ll of them, it doesn't cause catostrophic damage to the blade AT ALL.
so even if it was a chip, you can just forget about it and eventually it will sharpen out.

and what is petrified wood?

I was hoping someone would ask!!! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />


I started typing, but figured I should just go to Wikipedia and copy and past..... faster <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> ... and probably shorter and faster to read as well. <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" />

From Wikipedia:

Petrified wood (from the Greek root "petro" meaning "rock" or "stone", literally "wood turned into stone") is a type of fossil: it consists of fossil wood where all the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen. Mineral-rich water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay away, a stone mould forms in its place.

Elements such as manganese, iron and copper in the water/mud during the petrification process give petrified wood a variety of color ranges. Pure quartz crystals are colorless, but when contaminants are added to the process the crystals take on a yellow, red or other tint.

Following is a list of contaminating elements and related color hues:

carbon - black
cobalt - green/blue
chromium - green/blue
copper - green/blue
iron oxides - red, brown, and yellow
manganese - pink/orange
manganese oxides - black

Petrified wood can preserve the original structure of the wood in all its detail, down to the microsopic level. Structures such as tree rings and the various tissues are often observed features.

Petrified wood has a Mohs hardness of 7, the same as quartz.

Wikipedia mentions Mohs hardness as well. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> .... Notice - Harder than knife steel!

yeah yeah.... think how much time I waste typing....

wow
this thread is a older one

If you'd like to see some pics of some of my petrified wood, see here: Andy's Artifacts

I take it you've never been to the petrified forest park in AZ? I have pics there from one of our vacations.
