ANGUS MacGyver that’s my final answer!!
You wanna know why?
Think about it, here was working or not working for some shady weird organization.
He is a kinda secret agent with a difference.
He is quiet, mild mannered, deeply principled and refuses to carry a gun on his missions.
Fortunately, the last detail is unimportant when compared to his astounding mind.
Drawing on a vast practical knowledge of science,
Macgyver is able to make use of any mundane materials around him to create unorthodox solutions to any problem he faces.
The enemies of world peace and justice continually learn that underestimating this man is a fatal mistake for their plans.
You would have the adventures of a secret Agent, while not being an actual agent and you would be armed with almost infinite scientific resourcefulness.
I would also carry The Desert Eagle with that pocket knife.
Yours. “Secret Agent” Jay
