No, I’m not refering to Golf. Before the advent of Political Correctness, we used to use this word.
I’ve met a few people who have various impairments that prevent them from playing the whistle. Now there has been the idea of making a trombone like whistle - but that’s no fun trying to find the right note.
I discovered that after removing the tuning joint and the tonehole placement could be set so that a sliding tube fits between the fipple window and the top hole. It then slides down to cover one hole at a time.
A person with two hands could hold the whistle tip with one hand and slide the slide tube up and down to play. I could also modify the fipple so that a person with one hand could the whistle in their mouth and slide the tube with one hand.

Currently they are available in the key of High-D, more keys in the near future.
BTW - I will eventually have a Low-D for this and this might be good for people with small hands.
