Bought this 0.5mm diameter diamond coated wire from Aliexpress. Comes in various lengths but I tried a few at 1m packages (its pretty cheap). Seems to work excellent on composites which is normally brutal on any HSS blades. The G10 plate is in my scroll saw under power. The carbon fiber plate is in my jeweler hand fret saw. It comes in both larger & smaller diameters. I think its use is for lapidatr work, the word 'jade' comes up often. I'm sure there are other material applications for the stuff. Not sure how long lasting it will be, time will tell.

Go big or go home:
Concrete saw cutting contractors use diamond wheels usually 1 to 4ft in diameter, but some are also capable of using diamond wire. Usually diamond wire is for bigger (thicker) walls or difficult access or large concrete footings. Nice thing is that the cut is smooth and any imbedded steel or r-bar is no issue. I’ve seen this method used on a bridge demolition project to cut off 6 foot diameter bridge piers. The cut was horizontal and13 feet underwater. It worked great.

Cool! I suppose you could also use it in a coping saw!

Hmmm the folks in Greece will have you "hold their beer".
They use diamond cable miles long to cut Marble slabs off mountainsides. Slabs are 4-6 ft thick and thousands of feet high. They make these slabs into random handleable chunks by driving a wedge in at the top after the cut is done and topples the whole slab over to crash and breaks into smaller pieces.
I always get fret saw & coping saw & jewelery saw mixed up. I think (maybe wrong) fret saw uses clamped plain blades & coping uses pin style? Maybe one has swivelling heads & the other not? Thre are new NASA grade saws on the market now with other cool features, not sure how they fit into these categories. Anyway yes, my hand saw uses pin-less blades ~5" length? as does my Dewalt scroll saw. The picture cutting the carbon plate is using hand fret saw, the G10 is using DeWalt.
KnewConcepts saw. I like the blade retention system but yeesh the price. There are Chinese knockoffs but I actually dont use mine enough to justify an upgrade.

5" Mk.IV Heavy Duty Fret & Jeweler's Saw, Lever Tension With Swiveling
Designed to pull 50–60 pounds of tension on their blades, which makes it much stronger, and the blades vibrate less than our Mk3 saws. They are also thicker and slightly heavier, closer to the weight of a traditional saw, but still lighter. The saw is powder-coated red and is extremely scratch...

Ya kind of spendy! But I use mine often so might not be a bad idea if it lasts longer than the saw blades I'm currently using.
Looks like the MKIV is a thicker frame so if thats not a requirement, the MKIII is a bit cheaper. And remember these are CanuckBucks so 149 CAD becomes 105 USD. And its made in the USA so probably cheaper for those reasons too.
Looks like
I have inherited some good quality lapidary equipment (8” thin kerf power feed saw & 8” x4 cabbing polisher - both Raytech) so a jeweller’s diamond wire saw would be a nice addition. I have no lapidary experience & not sure yet how much or how deep the lapidary bug will bit - but a small diamond wire saw would be nice for other things too.
I found this on Amazon:
at $42 + buying some 0.5mm wire for another $20 looks good. I’d like your opinion on it and your explanation why the KNEW one you suggested above is worth 3x the $.
They both have a quick cam lock but the no-name Amazon knock-off lacks a swivel. Why is a swivel needed when a diamond wire is round and cuts on its circumference (with no leading edge)?
Thanks.
PS - am I comparing a Cadillac to an entry level Hyundai. They both get the job done but there is quite a difference?
You can even get Titanium frames (AliExpress). I'm not entirely clear why. It would be stiffer than aluminum but also heavier. How much tension can you pull on a skinny blade? I would think anything over 50 pounds would you even notice the difference? Must be some reason beyond cool kid on the block.
Jade pens. Wow the price. Now that would be a bugger to thread

Might not be real jade. Could be synthetic. Rock can be cut but......
I wonder what @Golem Pens or @CWret thinks.....
Jade has different types and they vary from a hardness of 6.0 to 7.0 on mohs hardness scale. At 7.0 it will scratch a knife blade but at 6.0 it might not (depending on the quality of the steel blade). Either way - it is very hard.
Jade can and is be used to make pens like the one Peter pictured above. But it is too brittle to cut threads. I believe the most common method used is to make a jade cylinder and then insert (and glue in) a metal sleeve that is threaded.
PS - Jade is either nephrite or jadeite. Nephrite is a bit softer and less likely to break when carving.

I just noticed the fine print 'celluloid jade' so some kind of synthetic plastic base

Yep that's celluloid - a particularly pretty if volatile plastic.
