Doing a bit of research on my favorite kind of steel backup. The humble steel washer stack of course.
I've tried different sized washers and have found 10mm x 24mm to be the sweet spot.
What's your preferred steel backup washer size?

Sick. I wish steganography was used a lot more in bitcoin. It's amazing tech.

I prefer washers for M3 screws with 1mm letters, as they are small and easy to hide. Here is the jig for these:

They look smaller than usual.
Have you ever had trouble fitting a longer word in it?

The jig features 12 positions. I numbered all washers with two digits to ensure the right order, so words with 10 letters do fit. Keep in mind that you just have to record the first 4 letters of each seed word to create a valid backup. Full words of course do look nicer.

Right, it looks nice & compact.
I'm surprised how small they are!

Wouldn't this also depend on the size of a person's letter punches?

It might. I haven't seen much variation in the letter punches.
BIP39 words are no more that 8 letters so at most you'd be using 10 characters on a washer.

Do you use a 3D printed holder for when punching?
I've found that when having to punch the same letter more than once, the end result gets rather messy.

I haven't so far, but I think it would make it easier & neater too.
I have an old iron shoe horn as a base. With the hammer I go one light hit, then one heavy. So far so good.

I mean, it’s just a steel washer, @Onions. What could it cost? $10?
