While perusing around the web searching stuff out, as you do, I came across this little beauty.
It's called the JetSlide, it's a solid Brass or Stainless steel rod that is attached to a ring that fits around your finger on one side, on the other side is a little flip leaver.
You wear it like a ring, and just use your pinky to flip the slide in/out of use....see video below.
I thought OOH, I gotta get me one of them, so I did a search on where to get one.
To cut a long story short, although sold at some outlets [at a premium ], I found the guy who makes them has a Ebay store

He has two additional items for sale, one is a copper sleeve that fits over either slide to add weight and a different tone to either the Brass or S/Steel slide bar, and Glass sleeves [you get 2 in a order], that again fit over the originals to give a different tone, these can be either glued in place, or use double sided tape as a temporary measure.
I went and ordered the whole lot at once, until I noticed that each individual item was attracting it's own postage cost...Oh no you don't [it would have been close to Aus $100 total after exchange rates ]
I emailed him and said what I wanted, he emailed back saying OK, he would adjust postage to suit.
And he did.
I received my two JetSlides with copper & Glass sleeves a few days ago..... I found I needed to bend the pinky finger lift for better fit, but all in all , recommended.
If interested, remember to tell him your ring finger measurement, he has a list at the bottom of the ordering page so you can measure in mm's to get correct size.
