Hey RTH Gang, Here is a knife I made from an old circular saw blade. I made it for a friend who is hosting a fund raiser for his Uncle who has been hit really hard by cancer. I know all of you can relate, as every family in America has dealt with this terrible disease on some level. My friend picked out the slabs, but I have no idea what they are. Any and all help identifying these slabs is greatly appreciated. Thanks in advance! John        |

The green looks a lot like the jade I used to make a sculpture. Don't know where it was found. I got it down at the gem club.

JOhn, Thank you sir. I spent considerable time on the blade. Hard to say exactly, but I would approximate 6-7 hours grinding and polishing the blade.
VJ, It has a jade look, but I don't think it is.
Snowmom, Thank you very much!

Beautiful knife for an awesome cause, BuiltonRock!  If it isn't jade, maybe it's serpentine, or possibly green marble with quartz? |

Thank you Ed! The blade was very old and I believe it was carbide.
Roy, Very nice compliment. Thanks!!
Nate, Thanks much. I hope it is a good addition.
Jan, You may be right on both. Serpentine is very likely for the larger section and Green Marble for the smaller. Thanks a million.

Right on John Old circular saw blades are some excellent material tensile strength and stand up to abuse some newer saws are just as good if not even better except lots blades now are made to be discarded and not worthy to be re-sharpened so that steel is not worthy I just attended the Arizona Knife Collector Association (AKCA) show here in Phoenix It was really fine showing Do you belong to a club ? anyway that blade you fashioned is seriously sharp piece handiwork !  |

The dark green slab definitely looks like the serpentine that I have collected at a quarry. But the serpentine varies in color at that location and there is anything from blue, black, green, and yellow. The lighter slab even looks like stone that I picked up there as well. That's a really great looking knife!

Ed, I do not belong to a club, but would like to learn more about metal in general. Most of what I know I learned here a few years ago when I was much more active on the board. Marriage, kids and work have cut into my rock time significantly. Trying to get back into it.
Thank you very much Mr. Connrock and Mr. Fossilman.
Roland, I believe Serpentine is right. Thank you.

BuiltonRockThe easy-peasy dif between serpentine and jade is the scratch test. They are chemically the same but the felting of the crystals in jade and serpentine are different. Likely due to slower cooling for serpentine. Take a scrap piece and try to scratch it with your pocket knife. Please do this, then report your results here. I am calling it jade. The felting seems very tight.

Shotgunner,
My knife leaves a scratch and so does a penny. When I shaped the rock on my wheels the snot was pretty milky. Seems pretty soft to me.

Nice work!! Not jade.
That is some really nice serpentine(like) material. Scratches with a copper penny is most likely softer than even serpentine.
Jade snot is milky-white too. Jade makes a better knife handle as it is harder and more durable. Serpentine will be fine for a saw blade knife.
