Bead Blasting and Corrosion

Yah it's me again, the cheesehead of knives! I've been thinking over my weekend purchase, as well as doing a little more reading. The M16 Carbon Fibre I ordered has an AUS118 blade with a bead blast finish. CRKT's marketing info says that the blade is "extremely hard, durable, tough and rust resistant". Is the rust resistant statement actually true, or just stretching the truth? Remember that I'm the guy that carves up walleye in the perpetually rainy Adirondacks. I'm wondering if I should remove the bead blast finish before I go poking wet food with this baby. And if so, what to remove the bead blast with. Would jeweler’s rouge do the job?

I also got to thinking, as I often do while reading magazines on the john, about that Tuf Cloth I ordered. Let me throw a little scenario at yah. I give my pretty new M16 a good rub with the Tuf Cloth, in preparation for some great fishing. Then I head to the mountains and catch that perfect eating size walleye... or trout... or perch... or some tasty little morsel of nature’s delight. So I gut this fish and cut it’s head off with the M16 in a barbaric fury of hunger. Scales fly everywhere, and entrails cover me head to toe, but the blade stays nice and rust free. Later on, the wife cooks up my forage on the charcoal grill and gives it (the fish not the charcoal) a taste. Will she tell me that it tastes rather... Tuf? What I’m getting at here is whether the Tuf coating is safe and tasteless when preparing food. I’d hate to go through all this work and have my own head lopped off for spoiling the meal!!!!! I can read the headlines now. "Fisherman killed with his own uncorroded knife, for the attempted poisoning of his wife."

Oh yah. Thanks for all the great responses to my last post. They made for some great reading, as well as some fevered panic. I checked out those Talonite blades and ZOIKS (as shaggy would say)!!!! That’s some big bucks, and I didn’t see any Talonite folders anywhere. Now if Camillus wants to make some good use of that Talonite corrosion resistance, they should look at making a Talonite folder with an added marlin spike. That would be absolute heaven to Navy Seals ..... and barbaric entrail covered fishermen. :-)
 
Buzz, sorry to say, but I think this is hype, at least when I bought a CRKT KISS and had it carried in pocket for 2 weeks carrying it and using it, it developed small spots of rust around the thumbob. I was not happy, that was the last beadblasted knife I have bought.

To me I feel that the beadblasting compromises the steel. Just think what would happen to your car if you drove through a sandstorm, but much harder blowing sand, can't be that good.

Just my thoughts.

If you want a Talonite folder, go to

PBKnife

and look under New products. The Gentleman's Folder IS Talonite.

Buzzbait, here are some facts you need to Know: beadblast is a finish that leaves the blade a dull gray; the advantage here is that beadblasts do not reflect light and are ideal for "tactical" purposes, it is also a less expensive finish.

stonewash is a gray or speckled finish which absorbs scratches well and more rust resistant than bead blast

satin finishes are shinier but less shiny than a mirror finish, they are much more rust resistant

mirror finish is the brightest and most stain resistant of finishes.

Note - ATS 34 and CPM 440V are at least two very high end steels that do not take mirror finishes very readily. If high corrision resistance is a high priority and you don't want to pay for Talonite, 440C and AUS 8 are two low cost rust resistan steels. A slightly more expensive steel that is pretty rust resistant is VG 10.
 
My CRKT Carson rusted like a fiend the first time i used it in less than dry conditions (hacking up moist plants.) Then I took off much of the nasty finish with some automotive metal polish, and have had no more troubles. Tuf-Cloth is said to be nontoxic when dry, I've used a treated blade to cut up food without any bad tastes, and so far no bad effects...

Buzz: If you use the Tuf-cloth, I don't think you'll have any probs with the BB finish. Definitely let the coating dry before doing any food prep with it. You can also buff the blade after the coating dries, with a clean cloth, and not lose any of the protective qualities of the Tuf-cloth.

You might try a search in the forums about the Tuf Cloth and food. The question has been asked before and the answer that I seem to remember came from the manufacturer that the Tuf Cloth is NOT FDA approved for use with food. However, they stated that the Tuf Cloth coating was non-toxic.

As for the Talonite folder, try: www.mayoknives.com and look at the TNT. This folder is a Talonite blade with Titanium handles. 100% impervious to rust. I carry one as my everyday carry and I never worry about corrosion.
