Triangle flush trim bearing

[ColeyS1]

Just flicking through the new cmt book and noticed this triangle bearing mounted on a flush trim bit.

Seems like a good idea ! last time I trimmed laminate my bearing became sticky from all the glue, if this works it would be much better.
Another thought, if this triangle bearing was used for flush trimming wood it would minimise tram lines from sticky/worn bearings.
Anybody used one before ?

I've used one but only for laminate trimming. I'm sure it would work with timber too just don't overload it

How's that going to work on internal edges at the corners?
