is Titanium in knives actually real titanium?

Google Ti 6Al-4v titanium alloy. Wiki has a condensed explanation of the grades (grade 5) and their most common uses. The Ti used in knives is most often an this alloy and not pure Ti. It would not be used on the exterior of a stealth.

I use 6al4v (Grade 5) Titanium alloy for my Ti knives.
This grade is what they use in airplanes, I think a lot of it is recycled from them actually. It is very tough, light and springy when bent.
6al4v Titanium is an aloy with 6% Aluminum, 4% Vanadium and the remainder being Titanium.
I weld Tungsten Carbide to the edges of my Ti knives, it is 72 Rockwell in hardness and makes for a long lasting edge especially on softer materials and cardboard.

Consider how complicated the steel in the blades can be. Humans are good at complicating everything that has a technical side of it, so if they can complicate steel, they can complicate aluminum and titanium. Almost all metals are alloyed with other elements to provide specific properties.

My skin is made from titanium and I'm not very stealthy. I tend to clank when I walk.

Not trying to be off topic, but do you think you could do a WIP demo of this? I have wondered how it was done and I would love to see it.

If you can't wait for Daniel to do a WIP then google "carbidizing" which is the process that applies the carbides. There are a few Youtube videos and websites on it. It really does make Ti cut longer.

I thought those were adamantium? Talk about a knife making material.

The titanium used for knife handles is 6Al4V titanium, probably the most common titanium alloy. It's stronger than aluminum and lighter than steel. It has many uses, from medical, to airplanes, to body piercings, to cutlery, to cycling, to almost anything where the end user wants something stronger than aluminum and lighter than. If a knife says that the handles or other components are titanium, it's the 6Al4V alloy.
That said, titanium makes for a rather poor blade material. Even the best alloys, such as Beta C, is rather crummy compared to even the worst of blade steels. Not all alloys can be heat treated for increased hardness. Don't believe what you see in the movies. A knife or sword made from titanium is going to be a hunkojunk compared to a steel one. Sure, you can sharpen it, and it'll cut, but durability and edge retention will be poor at best. Only when mixed with carbide edges do they offer more than a last ditch usefulness.
Also, ignore BS like Schick razor ads about titanium blades. They're not titanium. They're steel blades coated with titanium nitride (TiN), something that machining tools (and knives) have been coated with for years to improve durability and reduce friction.

I think you are confusing the Blackbird spy plane (SR-71) with the stealth aircraft of today. The Blackbird had a titanium skin to withstand the heat from prolonged operation at extreme velocity. That titanium was the same or similar to the material used for titanium framelocks.
One key benefit of a Hinderer is that the handle can withstand continual airspeed of 3000 miles per hour.

A stealth aircraft that had a titanium skin would not be very stealthily, mind you.
The fella said "be used on a stealth aircraft." He didn't say anything about it being the skin.
Yes, there is Ti on the 117. Likely some 6-4.
You don't use composite or aluminum next to the engines.
