In addition to printing and assembling the components linked
below, you will need a pencil, an eraser, and two Penlock shares
that belong to the same set.
The worksheet is used to write the seed phrase during the
recovery process. Other sections (shares) are left unused.
Note that each word is made of 2 gray boxes
(Penlock-specific checksum), and 4 white boxes (truncated
seed word).
The wheel is the primary tool for recovering the seed
phrase. To assemble it, proceed with the following steps:
Print and carefully cut out both disks.
On the colored disk, cut out the pointer window. The
smaller numbered windows are not needed for this
recovery process.
Attach both disks together at their center using a snap
button, a brass fastener, or a pin. Ensure the colored
wheel is placed on top and can rotate freely.
The wheel has 4 distinct sections that will be referred to
as follows: the pointer, the outer (character) ring, the
inner (character) ring, and the numbered spiral.
The wordlist might be needed to correct a specific type of
error. You can delay printing it until necessary.

Avoid pronouncing the results out loud
A. Identify the Recovery Window and Share Position
The recovery window you need to use depends on which shares you
are recovering from:
Inner Share
Outer Share
Recovery Window
Share 1
+
Share 2
→
Pointer (▼)
Share 2
+
Share 3
→
Pointer (▼)
Share 1
+
Share 3
→
Window 29→
Using the table above, identify the correct recovery window
for your shares.
Note which share is the inner share and which is the outer
share.
B. Recover the Seed Phrase
The seed phrase is recovered character by character,
sequentially. Proceed as follows:
Read the first character of the inner share.
On the wheel, locate this character on the inner ring.
Read the first character of the outer share.
On the wheel, locate this character on the outer ring.
Rotate the wheel to align both characters.
Read the resulting character from the recovery window.
On the worksheet, write this character as the first
character in the 'Seedphrase' section.
Repeat steps 1 to 7 for each subsequent character until all
the words are recovered.
C. Check & Fix the Words
Look up each of the 12 words in the sumtable. If you find a
match, the word is correct. You can then take note of the full
word when they are longer than 4 characters.
If a word does not match, an error has occurred — either during
recovery or when the share was produced or copied. Follow these
steps until you identify the correct word:
Repeat the recovery process from Section B for that specific
word. Pay close attention to characters that are easily
confused, such as E/F, O/Q, U/V, or X/Y. This may produce a
correct result.
If not, among words in the sumtable that start with the
same two grayed checksum characters, look for a
word that is similar but has one or two different
characters. This word is most likely the correct one.
If no match is found in the sumtable, use the wordlist to
find a word that matches the white characters but
has one or two errors in the grayed checksum characters.
This word is most likely the correct one.
Notes on Initializing a Wallet
A few important notes on initializing a wallet from the
recovered seed phrase:
Consult your wallet's documentation for specific
instructions on recovering from a seed phrase.
Enter only the white characters: the grayed checksum
characters are Penlock-specific.
Omit the dashes: they represent an empty character for
3-letter words.
Hardware wallets typically only require the first 4 letters
of each word, while software wallets often require the full
word.
