I am a very new knife maker and have a friend who wants me to make him a titanium fixed blade. So far it seems that i can make him one but it will not be very hard and that there is not an effective way to heat treat it... Is this correct? Is there anyone working on a new way to heat treat it to make it harder? Does Boker Heat treat their orion?
thanks

you can heat treat it to 45rc, approx. you try and talk him out of ti, it isn't a good knife metal. unless he truly does need it, military ect.
 
OK I'm another new knifemaker...and I'm curious what the use would be for a titanium blade, if it isn't very strong?????
 
Ti knives are usefull in the removal of land mines where nonmagnetism is necessary, and in some marine applications where absolute resistance to rust is required.

Not all Ti is the same just like not all steels are the same. There are steels (1010) which would make pretty poor knives and steels (most tool steels) that make great knives. Mission makes Ti knives and claims high levels of strength, 1000 lbs on the handle to fracture the blade for example, and great toughness. While I have not handled any of their blades, their are forum members that do own them and have made positive comments about them.

cliff, i think you miss understood, ti is very flexible and will return to shape, but the rc hardness is low, approx 45 when heat treated, mission knives sells to the military, so they need to have some ti knives. ti is very expensive, so unless it is neccesary don't buy one.
 
While RC hardness is an important materials property, it has to be kept in mind that all it measures is compressability. For the same steel you can usually make approximations on how strength/toughness vary with RC but you can't do it easily across different materials.

Talonite for example is also very soft, about 45 RC. There are quite a number of people who have been pleased with knives made from this, and makers who think it makes a good knife. It is also much more expensive than steel as well though.

talonite, unlike titanium acts like rc 65. it is becuase of adrasion resistance from the chromium, carbon, tungsten, and cobalt.
 
Exactly, you cannot simply based performance on RC. There are other properties to consider, specific to Talonite there are hard facing carbides present, specific to Ti, it is very ductile and tough with a strong memory.

If you like hightech solutions, a titanium blade with a titanium hardcoat would be a good idea.
The titanium would be corrosion resistant, and the hardcoat would, combined with a chiselgrind form the cutting edge, and the Titanium would wear and expose the cutting edge (in theory at least) and produce a "self sharpening effect, like the Benchmade 970ST.
I dont have experience with titanium blades with hardcoats, i am pleased with my Buckcoats, wich use a similar principle.
