Gave my Klean Kanteen a light sanding after 12 years

For anyone looking for a durable stainless steel canteen that can be used to boil water and withstand extreme use, this brand is a solid choice. It has endured numerous campfires and has even been used as a target for a Daisy rifle when I was younger.

Interesting trick I learned: I once dropped my canteen off a cliff. Later, I filled it with water, capped it, and froze it, which helped push out the dents. I then used a press to flatten the bottom.

Could I possibly use this method to fix a dent in mine?

@Sterling
Definitely try it and let us know how it goes!

I have an insulated version, so I can’t attempt it, but I admire the creativity!

@Sterling
Go for it! Just be careful with how much water you add. Too much might pop the cap off, too little and it might not exert enough pressure.

I’m concerned about potentially damaging the cap.

Caps are replaceable for less than $10 online.

True, but I’m attached to the original one.

Buy a new cap for the freezing process, then switch back to your old cap once it’s reshaped. Easy fix!

@Lex
That’s a good idea. I’ll start by experimenting with the cap off to gauge the expansion, then buy a new one if necessary.

The cap might crack during the process; I had to hammer mine to fix the dents since freezing alone didn’t work.

@Lex
I’ve decided to just keep it as is. The dents add character and tell its story!

@Sterling
It’s a common technique in metalworking. Definitely worth a shot!

That’s genius! I need to try this with mine to fix its stability.

Just a note, this method can damage insulation in double-walled bottles by compressing the insulating vacuum.

@Whitney
The original post mentions it’s a single-walled canteen, so that shouldn’t be an issue here.

@Whitney
Absolutely, never attempt this with a double-walled bottle. My canteen was single-walled as well.

Did you actually use it for target practice?

Yes, a long time ago with a BB gun. It’s been through a lot!
