may want to double check the legalities of carrying around an axe with you.
The Head (brand), "Arthur Ashe" model was one of the first composite "sandwich" design racquets produced. I don't think there was a wood model. Though, certainly not your point.Long ago where I grew up in the country, about 1960, a petite young lady was accosted by two gentlemen as she was walking home from the school bus stop. She was all of 5' 3" tall and put both of them into the hospital. In doing so she destroyed an Arthur Ashe tennis racquet. This racquet was wood frame with gut strings. I know of nowhere a tennis racquet has been listed as a weapon and therefore illegal to carry. Her father gave her the racquet and taught her how to use it. Her father was a career Marine. Neither the young lady or her father played tennis.
Tennis and squash racquets are now made of metal with metal strings. They are legal everywhere. There are over 3000 listed on EBAY between $30 and $50. Light weight, devastating impact, maybe a little weird but legal any where, (even on planes and public transport), Legal in non weapon areas. I sometimes wonder why no one else carries one as base equipment in a vehicles emergency kit.

ps I have never had to use a tennis racquet to stop a person, but you had to be there to see what it can do to a pit bull
What am I missing here?
Do you understand that water is incompressible and that when it fills a sufficiently rigid container without airspace that it effectively renders that similar to a solid of the same weight and shape? Metal won't expand absorbing some of the energy of impact, but neither will the Nalge and some similar bottles. The flimsy over the counter disposables will being too flexible. A full metal container with no air space will be better than a Nalge with no airspace, but not sufficiently so to make enough difference to matter.
At one time I put money into the Executive Sharpy - all stainless and looked good. You use it like a kubotan.
Where do you get a small vacuum chamber for next to nothing??
And how do you get the epoxy out of it once it's in it??
