Easy to use and heavy duty plate

Very heavy duty and straightforward instructions on how to punch in your words. Feeling much better with this reasonably priced superior alternative to paper!

Happy customer
Great product

And Jeff the CEO genuinely cares about his customers.


Ridiculously good product to protect your keys. This piece of metal is solid and feels like it will withstand anything. Heck it's so heavy it can probably be used as a weapon. I can now rest easy knowing my keys are secure and safe from any hazards.

Excellent all around

Great quality, great packaging, and easy to stamp. 100% good experience.

Easy to use

Simple design, easy to use, and great form of seed storage with simple punch out design to survive most natural disasters. Thank you!

Getting Started: Blockplate 24

Step 1

Peel your letter locator template guide from it's backing and stick it on your Blockplate.

Position the template as so the letters fall inside each box.

Step 2

With a marker, place a dot in each box for the first 4 letters of each word in your seed phrase (for 3 letter words, leave the last space blank/empty). Why only the first 4 letters? 

Double check each letter and word.

Using an Automatic Center Punch

In the next step, you will be using an automatic center punch to make a physical, permanent holes on your Blockplate.

To use, place the tip at the first marking where you want to make a hole. Press and hold the handle down firmly with increasing pressure until you hear an audible "click" (unmute video audio for sound). It should feel like you're compressing a spring until you feel a "pop".

We recommend picking up a center punch from your local hardware store or an online marketplace (paid link). 

Step 3

Using an automatic center punch, punch down at each marking.

This will make a physical and permanent indentation that will show up within each box.

Step 4

Peel the template off to reveal your seed phrase physically (and permanently) marked on steel.

Securely discard your used template. Repeat on the backside with your remaining words.
