I use them on leather for my chisels and plane blades

Would there be a difference between a pasted leather vs canvas strop?

I use mine on leather, either a hanging strop or a loom strop. I've tried it on linen but didn't like the sensation. I don't think there's much a difference as to effect though. For knives, I use balsa mounted on a board on a bench. There, I find it important to have a stable surface as the hand-held knife's angle can vary.

I prefer linen or canvas for razors and leather for tools and knives. Tools and knives leave a lot of swarf, leather can easily be cleaned, for smooth leather WD40 will clean and remove Chrome Oxide easily. For rough leather I scrape and lightly reapply.

Linen and canvas hold paste well and on a hanging strop flex and expose fresh grit, it does not take much to achieve excellent results.

Diamonds and CBN will cut deeper and leave a micro jagged edge, Chrome Oxide will smooth a Diamond edge. Diamonds can thin an edge to the point of micro chipping, where a trip back to the stones is needed.

Diamonds and CBN work great on tools and knives. For experimentation paste cardboard, inside of cereal box before you commit a strop to paste. Once pasted, it can never be fully removed.

Well, where I sometimes figured my finish wasn't 100%, the crox fixes everything for me.

Coticule -> crox => Amazing
20K -> crox => Amazing
Thuringer -> crox = Amazing

Even without crox these are some of the finest shaving edges I experienced, I know a lot of people had already figured it out, it just took me a little longer to try paste on strops. I don't regret it one bit.

I'd be happy with any of these edges, this crox really fills in a small gap that I was looking for, it adds that extra 1% that really does it for me. Outstanding shaves.

Yea, they did not want to say, it is just Chrome Oxide that we buy from Kramer Pigments, (or their vendor) at $5 per pound and mix with mineral oil and wax and sell to you at 100 times the cost.

For honing you do not need to add any other abrasives, it works just fine by itself. For polishing they add aluminum oxide to cut metal faster and polish, and it is cheaper than Chromium Oxide.

For most honers a stick or tube of any quality Chrome Oxide paste is a lifetime supply. My pasted razor strop was pasted, maybe 5-6 years ago, it has not needed any addition.

For tools and knives, I add a couple strokes of compound every couple of months, because of the swarf that tools and knives leave behind. I scrape the leather to remove the swarf and give it a couple of swipes from the stick.

i exactly do the same preparation.
