How to export a single private key from a crypto hardware wallet (Ledger, Trezor, etc) without compromising the entire 24 word seed. This process also doesn't require that you have access to your hardware wallet anymore...
Ideal for situations where you may have been mining to a hardware wallet and have so many small transactions (p2pool mining with things like Vertcoin will cause this) that your wallet software no longer allows you to send (or maybe even sync or view) the coins and they seem stuck. (Storing your Horizen stake for secure nodes or super nodes on your ledger will also cause this)
This method is also helpful for situations where you might have lost/damaged your hardware wallet and want to access or recover some of the coins on it while you wait for a replacement, or if you want to move coins and Ledger/Trezor servers/software are having issues. (While also not wanting to expose all of the coins on there by simply importing it into Coinomi)
This example uses Horizen due to its low value and fees, but it will work for any wallet/coin that supports BIP39/44, you will just need to use a different wallet to import the private key at the to send the coins, sweep alternatively, simply sweep a single private key using Coinomi. (eg: Bitcoin, Ethereum, Litecoin, ZCash, etc)
This video covers the process you would use to do it securely. (If you are totally unfamiliar with this stuff, please watch the whole thing first and don't just type your 24 word recovery key straight into a random website)
If you want to experiment with the 24 word recovery phrase I used in the video, if you recover the key, import the seed into the swing wallet (or a ledger) correctly, etc, you will be able to see the transactions that I made, without risking any funds.
Full notes as seen in the video are at the very bottom of the description.

Need a new hardware wallet?
Be safe and buy them direct from the manufacturer. (Not just through some random on eBay, Amazon, etc)

(You can even keep the same 24 word seed on your new hardware wallet)

Steps to Extract a Single Private Key from a Ledger Wallet
Or more accurately, extract a single private key from your 24 word recovery phrase...
1. Decide on the wallet/account/address you want to move the funds to... (znm1AkRXQcJwmnxfBv2PioSVFHQErWraSM3)
2. Retrieve your copy of your 24 word recovery phrase
3. Create an "Air Gapped" PC environment (eg: Tails Linux)
4. Download a tool to convert your 24 word seed to a set of private keys
5. Identify the public address that contains the coins you want, copy to a USB stick. (or use pen and paper) (znbfDn49M3btwcXi1SvYpnjPushXMA6ySzh)
6. Load up your "Air Gapped" environment
7. Import your 24 word key into a wallet (Web wallet can be fine)
8. Copy the private key you want
9. Import that private key into a wallet
10. Move the funds to a the next available address (or wallet) on your hardware wallet
11. Ideally, stop using that pubic address from now on, consider it compromised, or at least only as secure as any other software wallet...
