Do you think that you can make a blade with the titanium and have it perform better than the Busse knives?
As others are saying, it really depends on the use. I don't have a Busse knife, but it seems they are extremely tough. I have handled several of the large ones before at knife shows, like those ones that have blades the size of short swords.
There are be pros and cons.
Titanium pros:
-light weight, quick and easy to use (excellent weapon)
-really tough and resistant to gross deformation, even if thin
-stays sharp even under heavy machete use
-no rust
-shock-absorbing
-flexible but rigid and hard to bend
-high resistance to crack propagation, fatigue or breaking, shrugs off stress risers
-Differentially hardened
-ninja status over 9000
Titanium cons:
-lacks chopping/cutting power unless the blade is large due to light weight (for me the magic number is 18" - 28" of blade length)
-more prone to edge damage if you hit a rock hard or cut into a nail than tough steel
-Not as good against very tough things, like say, cutting sheet metal or asphalt roof shingles, or fish on the deck of a boat with steel beneath the fish as a cutting board; those things will dull the ti blade
-makes you look like a mall ninja
I'm not sure how to compare to a Busse knife, but these large ti alloy blades are really good hand tools, they function as blades wonderfully, and even knives seem just fine, better than a lot of common steel knives I use. The reason I make them is because
it's the only way to make a blade that conforms to my desires in large blade performance. Several ti alloys have some really stand-out attributes that are desirable in any sword or large cutting blade, not the least of which is the laser-like speed and accuracy of the blades in use and the extreme resistance to the type of damage that would render a sword unuseable, like a huge bend or break.
