Some of us loved having easily interchangeable (and relatively cheap - mostly $110/pair) blade runners. It made it possible to use multiple styles (e.g., freestyle, dance, synchro...), to pack the blades alone in checked luggage while you carried on the boots, or to send one set of blades back to a sharpener while you continued to use the skates.
To the best of my knowledge, only the Jackson Ultima brand offered them, at least for figure skates (speed skates and some hockey skates have had interchangeable runners for a long time).
The system included an aluminum Matrix mounting chassis, and separate stainless steel runners. Chassis + blade were lighter combined than most figure skating blades. Stainless steel blades retains an edge much longer than the high carbon steel blades MK/Wilson uses, resulting in a longer lifetime (though high carbon steel can hold a sharper edge for the first few hours).
It was an excellent product, though I like the MK Dance blade (with a smaller rocker and thinner blade) better than the the Ultima Dance blade.
Jackson has now discontinued the whole Matrix line, and suppliers are rapidly running out. (I helped - just ordered a few runners for my own use, BEFORE I posted this:roll:.
For those of us stuck with Matrix chassis, there is now a market for someone to provide replacement runners that fit.
For that matter, there is a market for someone else's interchangeable blade system for figure skates.
(Suggest: learn from Jackson's mistakes. Use a compressible cushion so the blade doesn't click against the mount, or sometimes fit very tight, due to thermal expansion/contraction. The tamper resistant nuts that Jackson used made them difficult to seat. Use a normal hex head nut or do it right - build normal threads into one side of the mount. The hex key driven bolt was OK, but a larger size would have been more robust. Or use lighter materials for the mount, like high end hockey boots. And I would love a dance blade runner more like MK Dance. But these are minor nitpicks.)
BTW, it is possible to interchange normal mounted blades, if they happen to have holes in exactly the same places. You have to do fancy custom stuff inside the boot, under the insole, so you can screw in bolts instead of screws.
