I was looking at Cabela’s thinking of getting a Grippy in D2 and saw a new item. It’s a Boker Cera-Titan. The blade is made of Sintered titanium.


“Sintered titanium blade is crafted by fusing titanium powder and extremely hard carbide materials into one uniform blank of metal that boasts all the durability, flexibility and light weight of titanium plus the incredible edge retention of ceramic.”

Boker Cera-Titan
 
The cera-titan idea appeals to me, but I haven't seen much to date talking about the its real life application pros and cons. If it's a choice between the two right now, I'd stick with the proven commodity of the D2 Grip.
 
I wasn't thinking of getting the Boker, I just never herd of this before and found it interesting.
 
Since Cera-Titan seems to be the most advanced titanium based blade material, maybe one of the knife mags could do an article based on destructive tests comparing Cera-Titan to top blade steels, e.g. S30V......Edge holding while cutting various materials......Resilience.....Toughness & impact resistance, if applicable.....bend-break tests, etc; And evaluate this new blade material for appropriate use.
What happens when such a blade is expose to flame?
Does anyone know of such research?
 
Its made of a Titanium Metal Matrix Composite with the Matrix being titanium and the reinforcement likely being Silicon carbide, titanium carbide, tungsten carbide, etc. This material has other uses for in components that require light weight as well as extreme wear resistance. (ex. Track shoes for armoured vehicles). I have no knowledge of how well it would perform as a blade as the matrix, titanium is inherantly quite soft and if the carbide particles are in high enough concentration to bring the hardness to an acceptable level it might make the knife very difficult to sharpen. Overall I don't see the need for anything but a steel blade, excellent toughness, wear resistance, hardness, fracture toughness, etc.

Offhand, I can think of four reasons for considering improved or altered versions of titanium.
1. Completely rustproof.
2. Forty percent lighter than steel.
3. Non-magnetic (useful in certain military applications).
4. Greatly increased edge-holding ability.
I own a Boker Cera-Titan folder and know from experience, it is easy to sharpen with ceramic rod, as recommended by Boker.
