I’ve been playing a lovely David O’Brien keyless flute for close to a year now, fully-lined w/tuning slide. It’s my primary flute right now and I really enjoy it a lot, an easy player with a sweet tone in the upper register. It’s the first flute I’ve owned with a tuning slide and lined head. But, every now and then (like today), I pick up my trusty Casey Burns (large-holed, standard keyless model) flute that’s completely all-wood – unlined, no tuning slide, no rings, and fall in love all over again with that au naturel sound and feel – that quintessentially warm, woody, soft tone. There’s just something special about nothing more than breath, wood, and fingers connecting player to sound.
Stiofan, variety is the spice of life. I totally agree.
One of my favorite flutes is an all wood Martin Doyle—in beautiful rosewood. I really notice the tonal nuances and enjoy the mellow woodsy sound. Not less powerful, but smoother and warm with its own unique bark. Every time I pick it up after playing my tuning slide lined flute, I am pleasantly reminded of the joys of a completely simple flute— interesting and compelling to play.
My “pry it out of my cold dead hands” flute is an old all-wood Nicholson rosewood by Pat Olwell. I have a fully keyed boxwood version that’s close but not quite the same. For my arthritic hands, the weight or lack thereof is wonderful, but there’s just something about the way it plays that’s different from any other flute I’ve owned. I agree that the sound is just somehow “woodier.”
I do like all wood Flutes
Two Flutes that come to mind are The McGee GLP’s as well as Martin Doyle Flutes without the metal Slides
I can’t say they sound better than the Flutes with Metal Slides, but they do weigh less which is a big Plus.
My First Flute was a Sweetheart 1 Key Flute which did not have a metal slide, but it did serve me well.
I think Players fall in one of two camps , People like myself that don’t play in many groups and don’t need a slide, or those that play
sessions that benefit by the fine Tuning of a Slide
But there again Martin Doyle’s Flutes without a Slide seem to be fine in groups and allow for some fine Tuning 
This could easily turn into a Martin Doyle flute thread—a worthy topic. I did read somewhere (on his website?) that Mr. Doyle favors a flute without metal slides as the tone is more to his liking, or something like that. He definitely accomplishes instrumental magic with his all wood flutes. Mine is his two piece model that seems to adjust tuning within the tenon space just fine. So much fun to play!
I have a two part Casey Burns folk flute in Mopane. It really is just a two part stick with a whisky bottle top as an end cap. The functional “cork” is a bit of thread wound wood. It has a very lovely minimalistic ethic to it and sounds good too. I need it about a quarter inch out to play at 440Hz at sea level and I have a small plastic pipe spacer in the joint to hold it roughly there. I also wound the outside of the mortice with some fishing line and super glue since that seemed the weakest part of the whole flute - it is all transparent, so you hardly see it. (Today, I might have used carbon fibre thread and gone with a black adhesive for a minor contrasting look.)
So, functionally and aesthetically all wood with no decorative carving/turning and sounds great. Yes, I can understand the appeal people here have described with all wood flutes.
The reason it isn’t my main flute is that I have a fully keyed one that I like better and use chromatically and another superb keyless that has a proper tuning slide which is sometimes essential as soon as I am in differently tuned company, e.g. mountain hut, or accordeons/pipers.
Hear hear!! I don’t want to steal Chas’ earlier post, above, but I have one of these gems for sale. Nicholson design, rosewood, made by Olwell this year. Ivory inset in the crown. Plays perfectly in tune, clear and loud in a session, and a joy to hold because of its light weight. Comes with a brand-new, padded cloth case.
I will be happy to send a picture and in any case I will be posting a picture or two tomorrow. It was destined to go to Ireland but plans change so I am offering it here for $1,300 + postage of about $25.
What Chas says bears repeating:
My “pry it out of my cold dead hands” flute is an old all-wood Nicholson rosewood by Pat Olwell. I have a fully keyed boxwood version that’s close but not quite the same. For my arthritic hands, the weight or lack thereof is wonderful, but there’s just something about the way it plays that’s different from any other flute I’ve owned.

If Chas objects I will delete his post. Enjoy the holidays and Happy New Year to everybody.
No complaints at all, David. I agree with everything I said, and I’m all for great flutes finding homes.
Thanks Chas… the flute sold almost instantly.
