Hello again Chiff and Fipple! So I’ve been continuing my research into tin whistle playing and I’ve been hearing about something called “Pipers grip” and I was wondering, what is this exactly?
Admiral, can I suggest you also do a Whistle Forum search or Google search? You’ll find many posts and discussions, including several from just the past few days. After, if you’re still unsure, feel free to ask for details.
Edit: Changed my mind, leaving the thread open. Have at it. 
There is a very effective “Search” function at the top right of the forum page. Most everything has been asked and answered several times.
The C&F forums and the rest of the world wide web can also be searched. And you don’t have to login, start a new thread and then format a complete sentence in English to enter a search. It’s amazing really. You should try it sometime.
Step-By-Step. There you go.
And the name has recently been changed to Super Duper Easy Grip.

may you live to regret this

Perhaps we could do a thread on pipers grip using the format of “Call my Bluff”:

Nobody knows exactly!
depends on the piper
Looked at my partner’s jar of instant coffee this morning and it proclaimed “EZ GRIP!”
I thought, “damn, now I’ve got to use the bloody piper’s grip on the coffee container too?”
Piper’s was a brand of tobacco popular with sailors until it was banned due to containing very high levels of addictive chemicals that are hazardous to health. Smokers who used to buy this brand found it very hard to quit or swap and often came down with symptoms including memory loss, shaking, fits, convulsions and a nasty rash when wearing wollen socks. The condition was known as “Piper’s Grip”.
In the late nineteenth century pipefitters worked with tubing and soldering agents that had a high content of lead. Medical practice being what it was in those days did not associate the effects of exposure to lead as they do today. Some of the symptoms were indeed outwardly subtle. But those close to the tradesmen, spouses and children mostly, recognized the signs of poor appetite, weight loss, diarrhea and constipation as being effects of the work and referred to it as “the Piper’s Grip”.
