There's been a lot of hype about Talonite. It's been touted as some sort of super blade material. First off, there is no reason to expect it to take an outstanding edge - it is NOT a hard material. A Talonite blade has an RC typically of 48 or so. It does not have the potential to take or hold an edge as well as top-of-the-line knife steels.
Talonite has only slightly more than half the strength of premium steels, so it is less able to withstand rough use and abuse. These are NOT just my opinions, you can check out the material properties yourself.
Given that, the material will NOT corrode. It holds an edge very well for certain types of cutting, such as fiberous materials like cardboard, but NOT hard materials.
It has its uses, but it is VERY expensive. And, yes, I own two Talonite-bladed knives and can talk form personal experience as well.
