It is pretty amazing how many things that can be built with the tool set you have there, although a larger handsaw would be a great addition. I think the most versatile hand tool is the chisels. Together with a hammer they can do just about anything, albeit very slowly in many instances.
While in the Navy back in the late 50’s my ship visited Okinawa and I spent some time driving our captain around Kadena air force base.
