Traditional white compound better at burr removal even with super steel?

[yepimonfire]

So an interesting observation I've made as of late is that white rouge appears to be significantly better at deburring stuff like 10v, K390, M4 etc etc than diamond compound. Obviously it is useless for actual sharpening or "mirror edge" polishing but after using multiple different diamond compounds in varying grit sizes I find myself going back to white rouge because it just works better and faster. I'm talking something like 10-25 per side and the burr is basically eliminated. Obviously I've had absolutely no problems deburring low alloy stuff like 8cr with it either but even using diamond on that kind of stuff doesn't work as well if the main goal is deburring.

Anybody had a similar experience or have any idea why this might be?

Because Diamond can create a burr if / when you ( over ) strop . So say some who have looked more deeply at stropping . ( Well , people say stuff )
But that's what I have hears said ! ( For what it's worth ? 5c / 50c / $1 - Who knows )

I feel that white compound ('white rouge' in aluminum oxide, specifically) is best-suited for fairly ductile ('bendy') steels that produce stubborn, flexible burrs. Most steels like this I'd think wouldn't usually fit into the 'super steel' niche. Most of the super steels, I tend to believe, will usually produce burrs that aren't so ductile and can be stropped away by simpler means, or even eliminated almost entirely on the stone.

Because very ductile steels produce those stubborn burrs that'll flop back & forth all day long, the white compound seems to work very well in abrading them away or making them so thin & flimsy that they'll easily tear away from the edge in the first cut in anything, even in paper. Steels like 420HC or 440A at low/medium HRC (mid-50s), or even steels like ATS-34 or VG-10 at mid/high HRC (high 50s to 60 HRC or a little more) fit into that 'ductile' niche, based on my own experience with them.

And my best use of white compound is on a denim strop. You can heavily load the fabric with the compound, to a very dense application. As such, it'll be very aggressive at stripping away very tough burrs and polishing very fast, if you're pursuing that. A 24" paint stir stick with denim adhered to it (contact cement) works very, very well as an aggressive, polishing, burr-destroying beast of a strop, with white rouge.

This is how I use it (denim). I do agree it's great for difficult burrs on softer steels but even on something like k390 (that can be 99% deburred on a DMT XF) the white rouge seems to remove the roots of the burr giving an insanely clean edge that I can't get with diamond paste. The edge finished on diamond just feels and cuts like it's blunter, and as a bonus, the white rouge leaves most of the teeth intact giving an edge that can both split hairs and saw through zip ties and rope.
