Poor Cutting - Titanium alloy is NOT a good substitute for a working knife blade because it is not hard-enabled to adequate levels. In addition, it does not hold an edge for repeated use because of the lack of carbides.
Disadvantages of Titanium
The primary disadvantage of Titanium from a manufacturing and engineering perspective is its high reactivity, which means it has to be managed differently during all stages of its production. Impurities introduced during the Kroll process, VAR or machining were once near impossible to remove.
In short, titanium is best for lightweight and high-temperature applications, while stainless steel is better for cost-effective, general-purpose use.
Titanium is not a good knife material. While it is relatively high in hardness, a blade need a very high hardness to keep an edge. Titanium blades are only used for corrosion intensive environments like for diving knives. Not to say that Titanium is very costly. 10 to 20 time the price of blade steels.
The service life of a titanium nitrate blade can be up to four or five times longer than that of a steel blade. Using titanium nitrate blades for cutting tube and pipe has numerous benefits in orbital cutting.

Carbon steel, more specifically high carbon steel (0.8% and above) is well-suited for bladesmithing. The high amount of carbon present in the steel provides the toughness, strength, edge-holding, and corrosion resistance necessary in a great knife.
When it needs sharpening, 100% titanium must be entirely re-ground afresh, and not just have the cutting edge re-honed like that of typical high-carbTitanium knives may be difficult to sharpen due to its hardness, but it holds its edge for long and is characteristically maintenance-free. ...
In applications requiring light weight, corrosion resistance, biocompatibility, and high-temperature resistance, titanium can be a better choice than steel. This makes titanium ideal for use in aerospace, medical devices, chemical processing, marine, and high-temperature industrial applications.
Carbon steel knives are often the sharpest steel for knives. They're sharper and harder than stainless steel knives. An authentic carbon steel chef's knife is exceptionally sharp, but it is also vulnerable to chipping if not used correctly.
Titanium is a softer metal that is more prone to scratching but stainless steel is the most scratch-resistance. Titanium is lighter than stainless steel, while stainless steel is heavier. Because of this differences, both the metal's characteristics may be tweaked to each other and make it both viable options.
Titanium cutting boards are gentle on knives. They do not dull the knife quickly. This means your knives stay sharp for a longer time.
Titanium is not a usual material for a knife blade. It is not hard like knife steel and will not hold an edge. However, Titanium does possess some outstanding properties that steel does not. Titanium is virtually unbreakable.
Other metals and materials typically last 20 years, while titanium pipes have an average lifespan closer to 40 years. Many of the properties that make titanium ideal for power plant condenser pipes also make it an ideal metal nuclear waste storage containers.
Health effects of Titanium
Although it's believed that the body can stand large amounts of the metal, there are several consequences of being exposed to too much; including tightness of the chest, chest pains, coughing, breathing difficulty and skin and eye irritation.
Titanium Dioxide powders or dusts are not compatible with OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE) and STRONG ACIDS (such as HYDROCHLORIC, SULFURIC and NITRIC).
The recent discovery that titanium undergoes time-dependent degradation, or biological aging, has provided new insights in biomaterial research with significant potential for therapeutic impact in the field of implant therapy and reconstructive medicine [1,2,3,4,5,6,7].
With its much higher melting point than steel, a maximum of 1650 degrees Celsius, titanium will hold its shape under almost any circumstances a human will encounter. As it is very stable and solid, titanium has become an excellent material for watch cases. However, titanium watches scratch easier than stainless steel.
Titanium, however doesn't stand a chance against bullets fired from high-powered military grade firearms such as those used to penetrate tanks. Titanium can take single hits from high-caliber bullets, but it shatters and becomes penetrable with multiple hits from military-grade, armor piercing bullets.
It's just some, like ceremic knives, are hard and brittle and need special equipment to sharpen them, like diamond Lapping. Ceremic blades are harder than normal honing stones, so, will not make any sharpening effort. However, pretend rubber knives are only for show and definitely cannot be sharpened.
The biggest pro for titanium knives is that they are more corrosion resistant than steel. This is especially useful for divers, who will carry the knife of long periods of time in highly corrosive ocean water. Another pro is that titanium is lighter than steel. Reducing weight can help reduce strain during knife use.
In this instance, titanium could be a good compromise as it's strong (albeit not as much as tungsten), corrosion-resistant, and lightweight. Tungsten's 142,000 psi tensile strength is stronger than titanium's 63,000 psi, but titanium has a better mix of strength and lightweightness.
Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. have extremely high edge retention.
For achieving exceptionally sharp edges, CPM S30V and CPM S110V steels are highly regarded. These steels are designed to maintain sharpness over prolonged use, making them perfect for applications where precision cutting is crucial, such as in fine culinary tasks or detailed crafting.
Due to its longevity and wear resistance, machine knives made from Tungsten Carbide will last longer than blades made from steel, so it may be worth considering the cost of steel replacements and deciding on a material that way.
