This video provides all you need to know about the straight Morse keys or Morse code keys. These are the types of Morse key that have an up and down action, and are sometimes called pump handle keys for this reason.
These keys have undergone a lot of development since the first ones were introduced back in the early days of Morse code.
Today there's an enormous variety of Morse keys or Morse code keys available and in this video we'' explain what these keys are, the many different types that are available and we'll explain what you need to look for when buying a new one.
There are many options to choose from. There are many new ones ranging from the low cost ones to mid range and to the top range, and we take a look at these to see how they perform. The mid range is a Hi-Mound key and the top end one is a Bencher.
However we also take a look at a variety of older keys including a steel lever key, an old British Post Office (Walters Electrical) Morse key, and the WW2 British army keys: the WT-8AMP.

Thanks for a good, complete description. I still own my first straight key - a surplus J-38 that I paid 75 cents for in 1957.

I see many of these old military type keys on eBay and other videos but nobody says what is the other lever for? Can you explain it? Thanks. 5:01

The slide lever associated with the steel lever keys was primarily required in the old days of the telegraph. The contact had to be close when not sending so that the other end could use the line and send messages back. If it was left open, then no current could flow and the other end could not send. For use with radio transmitters the slider was closed when tuning up, but it is not really a requirement these days on most modern transmitters that have a tune button.

Sadly, at the end of your video you say there is more information on the description but because of the hashtags the [more] link can’t be activated, one either activates the hashtag or access your profile.

I've tried replicating your problem, but I can access the profile and description on both mobile and desktop. I'll investigate more. Thanks for flagging it.
