I’d never buy a titanium bladed knife. I don’t understand what the allure is. My suspicion is that it’s a marketing ploy to rope in the uninformed. Knife ignorant people who hear “titanium” and drool.
I believe there are a few titanium alloys that can function as a blade and compete with steel, such as SM100 (titanium/nickel). However the price of these makes it an exotic material for now, not for mass production yet. There’s also a company named Vargo that produces titanium/silver/ceramic blades, but I don’t know the toughness rating of such an alloy.
The linked eBay item is either a Kershaw Leek or a counterfeit of one. Omega 17 has a point. Some sellers or manufacturers will occasionally list the blade material as titanium when it has a titanium-based coating. I don’t think I’ve ever seen Kershaw do that. For the item in question, does the blade even look like it is coated?
Something else to consider is that it would be very strange to see anything as exotic as a titanium blade paired with clunky stainless steel scales, much less sold for ten bucks.
It’s already been said but titanium is not a good blade material. Neither is iron. Steel works because it is an iron alloy with various substances forming microstructures within it. Carbides are crucial for steel as we know it.
Picked up this cheap MTech 882 as I wanted something small to fit in the 5th pocket that also has a bottle opener. Not sure what kind of steel this is, but at $6-$7 I’m not picky. Overall, it’s a pretty sturdy knife, although a bit heavier than I’d like.
This is some Kershaw knockoff, from what I understand.
