Left handed tape measure?

[BotusBuild]

Have I got a left handed tape measure, or am I supposed to mark with my left hand?

Does it match the left handed Stanley knife?

I've also got a spirit level that is incorrect on the vertical at one end.

 

 

The house is called "Crooked Lodge".

 

For clarity, I am mainly right handed but with a reasonable degree of (made up work incoming!) ambidextriosity.
