Titanium is a material with a superior weight-to-strength ratio but is actually quite soft in its pure forms. Try bending a titanium spoon. It is much easier that one made from aluminium. The titanium version of the OCTO carabiner is made with the very popular Ti6Al4V titanium alloy also called grade 5 titanium due to its higher strength and stiffness compared to the pure grades. Some properties of Ti6Al4V are:
Yield strength: 880 MPa
Density: 4.4 g/cm3
Hardness: 36

For the steel version of the OCTO carabiner the surgical grade 420 stainless steel alloy is used for its superior qualities. Some properties of 420 SS are:
Yield strength: 1360 MPa
Density: 7.8 g/cm3
Hardness: 57

For the aluminium version of the OCTO carabiner the aerospace grade 7075 aluminium alloy in T6 temper for maximum strength. Some properties of 7075-T6 aluminium are:
Yield strength: 480 MPa
Density: 2.8 g/cm3
Hardness: 87

This is your answer.

The Kn rating of the Ti Carabiner is 56 - which equals 560 kg. Steel and Aluminium is slightly less but will hold in even the most rugged situations that you thow at them.
Remember, it is not to be used for climbing or as PPE.

This is your answer.Yes, the OCTO multitool is TSA compliant and it is allowed to bring it in your carry on luggage.
According to the TSA:
"Multi-tools that are less than 7 inches in length that don't contain knives are allowed in carry-on bags." - We have brought it along on several occations with no issues.

Although, please remember that the final decision rests with the TSA officer on whether an item is allowed through the checkpoint. This also apply for items on the not prohibited list.
