Titanium Blades???

[tonydahose]

i was watching Dinner Impossible with the mrs tonite and the english dude brought out these knives and made a big deal about how they are so much sharper than what the person that was going to be using them is used to. i did a quick search and it looks like it is probably a titanium coated high carbon steel knife. so it looks like they use the titanium for strength, corrosion resistance, and edge retention...is that everything and or correct? my next question is how much sharper are these knives to us knife nuts?...i am guessing my santoku is just as sharp after i get done sharpeneing it..or damn close. right???

...it looks like they use the titanium for edge retention...

I don't think so. Ti is the least material I would use when I wanted a blade with good edge retention. Usually it's softer than steel - much softer. Pure Ti6Al4V will take an edge that is just as sharp as the edge of a steel blade but after one or two cuts through cardboard it's gone :D

It's probably titanium carbide coated like Warren Thomas' blades. Which is of course not the same thing as Titanium. From what I understand it's kinda like Java and Java Script. They share a similar name but are quiet different. I think it's also a bitch/impossible to sharpen when it finally does get dull.

For Warren Thomas' stuff which is all made for SD purposes, limited use against soft materials, it makes sense. It also makes sense for disposable razor blades. For kitchen knives? Not so much.

I'm mostly talking out of my backend here based on what little knowledge I have. I'm sure someone else can be much more specific and accurate.

Titanium nitride is very hard and a very thin coating. It doesn't make the piece sharper. It only gives the initial edge some more longivity. It does bring extended life to drill bits and taps that you are not likely to resharpen, particularly when precision is required. After a few passes on the ceramic of diamond hone and the 1-2 micron coat is gone...Take Care...Ed

many of Laci Szabo's knives are made with titanium.

I notice they are also quite expensive!
