high carbon steel for food

The Tuf-cloth chemicals are not food safe, but the amount of chemical left on the blade after using the cloth and wiping the blade down would be so minute that it should not cause any adverse effects on most people. In reality we ingest more harmful chemicals by breathing and living our normal lives than you would get from a blade cleaned with the Tuf-Cloth.
Just my opinion of course from being around chemicals and other "baddies" for 70 years.

interesting. Do you know how well the cloth does at keeping a patina away, or what happens?
 
I have no experience with the cloth myself. The quote about the chemicals was from another thread a few days ago about the Tuf-Cloth. My guess is that the Tuf-Cloth is a rust preventer, and may prevent a patina from forming unless the solution cuts and removes the cloth residue from the blade. Whether it will remove an already established patina, I haven't a clue. Good question though. Maybe someone with actual experience with the Tuf-Cloth will chime in and we will all learn something.:confused:

There's some info on the mfr's site stating that the Tuf-Cloth's treatment will not remove rust, so I'm sure it won't remove patina either. And if it really does help to prevent rust, then I'd think it should prevent patina from forming as well (both need oxygen exposure to happen, and rusting additionally requires moisture).

This is quoted from the FAQs on the manufacturer's site, for Tuf-Cloth:

Will TUF-CLOTH remove rust on my equipment?

No, TUF-CLOTH is not a rust remover. You can use TUF-GLIDE on some synthetic steel wool to remove surface rust. If the metal has severe rust you will need to use a rust remover (we find that naval jelly works well). Please keep in mind that rust removers may also remove finishes from metal. Once you have removed the rust, use TUF-CLOTH to keep the rust from forming again.

Also, for food use, from the same FAQ page (I added the bolded emphasis to the last statement):
Can I use my TUF-CLOTH treated knife to cut food?

None of Sentry Solutions products are FDA (Food and Drug Administration) approved. TUF-CLOTH's protection bonds to metal surfaces. This bonding reduces the possibility of transferring material to food items that might be cut. If you plan to cut food with a TUF-CLOTH treated blade, we suggest that you wash the blade first.

These days I use a carbon steel kitchen knife most of the time. It's shirogami #2 steel (laminated with some other carbon steel, I guess). It does have a forge finish (? kurouchi), but a fairly big part of the blade is still exposed. I generally don't cut citrus (or fruit in general) with it. I tried to force a patina on a carbon Mora with some lime I had left over and what a stench. I haven't noticed anything along those lines when cutting veggies and meat. The blade will get a patina from the contact with the food, but I wash it and wipe it down after each use and I haven't had any noticeably come off in the food or leave any kind of taste in the food.
