I just got off the phone with Benchmade, and first off they told me that they did 50 42's on friday....so that means that production is picking up..YAY!!!

Now...about the 42a...would you really want some funky looking color you can't really customize?? Why not just take the knife somewhere that does anodizing(I hope i spelled that right) and choose your own color....I'd personally love a bright yellow..specifically the Lead Chromate precipitate when you mix Pb(NO3)2 + K2CrO4...

I think thats what I am gonna do...my own custom 42...
 
I want purple sir.. what do I do? Do I have to ask the custom shop to add chemicals?? I was under the impression it deoended solely on the heat and duration of heating.. but I am no chemist I only bend steel

Here is a pretty good synopsis of anodizing...I don't know if it will work on titanium though...this may be for aluminum only...

however..in order to do it they would need to take apart the knife to dip the handles..and that would prolly void your warrenty...

If you want purple, i know that KMnO4 (Potassium PerManganate) is purple...but this is an aqueous solution, not a salt...

that's about the best i can do...it's been a while since i've had chem...

I had a Paragon auto aluminum handle I wanted re-anodized and the envirmental laws are so strict,I couldn't find anyone in the area that anodized.When I did finally find someone in another state(CT) The company wanted $100.00 to anodize these little handles.Believe me guy's,its much cheaper and easier to wait and get the colored ones from BM.
 
Yeah...I've called a couple places and they all have a minimum charge of $150 or so...thats just rediculous for the amount of titanium involved here..

I wrote Roberta DeAsis an email over at Benchmade asking if maybe they could get a Benchmade authorized titanium anodizing company that would do it for us without braking warranty, and hopefully at a lower cost....he replied that he'd go ahead and forward it to the correct people to look into it...

these are who she forwarded it too..

Maybe if whoever is interested also drops them a line they'll see that it may be worth it...so I urge whoever is interested to email them and let them know.

Thanks guys.

I don't remember where I read it, but I remember seeing something on the BM42 saying that is an electrcal current that is passed through the Ti that changes the color. Depending on the voltage it will vary the color. If I can find the article, I will post the link.

When you heat titanium, the metal changes color very quiclkly, but you get a rainbow effect,if cooled quickly it will remain that rainbow color, if you want one solid color, you must rely on anodizing, which is similar to metal plating.

Anodizing is primarily used on nonferious metals, Remember the frame on the early model 39 and 59 S&W double action semiautomatic pistols, their aluminum frames were black anodized to go with the blued steel slides
 
When anodizing titanium, niobium, aluminum, etc., electricity is usually the 'carrier' of the color. As the voltage changes, so does the speed of the 'plating process', plating meaning a surface deposition of only a couple of millionths of an inch- that is also why it wears off. The color actually comes from light reflecting off of the surface and changing the spectrum or frequency at which you see it. You start anodizing at the higher voltages and those colors stay the same, as you get different colors as the voltage lowers, or something like that.......................... The black anodizing is a chemical reaction to the aluminum almost like parkerizing.

I've read that one form of anodizing on titanium is just like chroming your bumper...

I am sure that will last a while...and maybe if we can get a cheap enough place to do it for us, it won't be to much of a hassle to send it back to be redone if it wears off???
 
Here's what I got so far..I first submitted some questions on an online form, and I can't remember exactly what I asked...but this is the response i got..
-----------
Without actually seeing a handle with the representative finish it is rather
difficult to give you pricing. Also, you did not specify whether you are
intending to do type II anodize which is the slick gray coating or color
anodize. A ball park figure for a handle would be araound $1.00. I would be
happy to do samples for you.

Then this was my reply:
I can't remember exactly what it is I wrote in your email, i've sent out alot...
Here is a link to a picture of the Item.. http://www.benchmade.com/bench/catalog/customs/custom-bali-Song.html

I am assuming that I would have to take it apart so that the blade doesn't get anodized too???

What I am hoping for is a bright yellow anodize. I believe that Lead Chromate is a bright yellow.

I would like whichever is the strongest and longest lasting anodizing.

Can you give me pricing on all the different types, and which is the best??

Thank You,

Then I got this as a reply:
Raffi:
Titanium anodizes in various colors and a yellow or gold is available. I do
not know how successful it will be with cast titanium, assuming it is a
6Al-4V alloy as the substrate. Titanium anodize has no dye or imparted
pigmentation nor is it the result of chemical reaction. It is an oxide layer
the thickness of which provides the perceived "color". The blade will most
definitely have to be removed as steel does not "anodize". This coating is
generally cosmetic and does not have great durability. Again, I would do a
sample for you if you like and you can assess the possibility further. This
handle would be about $1.00 each piece to anodize yellow.
Regards,
Bill Grossett
---------------------------------
anyone know how I can get a sample??

There may be some promise here yet...

He does say it wont have great durability, but at $1.00 per handle, you could always just get it redone right?? maybe??

Most commercial anodizing companies probably aren't willing to undertake onesy-twosy orders. It takes considerable time and effort to set up their equipment and "dial in " their processes. There are fixtures and jigs to be considered, etc. Furthermore, their equipment and their tanks are geared toward large volumes. For a small piece like the handles on a 42, their tanks are large enough to do a hundred pieces at a time. It costs them just as much to do one as it does to do 100, so the cost you'd pay will probably be quite large.

Now, please understand there are certainly exceptions to this rule out there. I'm just talking in generality here.

The good news is that anodizing isn't a complex, difficult, expensive, or especially hazardous process. My office is a mess, but I have around here somewhere an article that describes in exact detail the processes. It's certainly within the reach of do-it-yourselfers. I'm certainly going to be experimenting with it.
