Various photos of my knives. Some are at a good angle (Para, Centofante, UKPK, Trance) others could still be thinner (Spin, Tenacious, Queen Stockman). When I have more time I'll make videos of how well these knives can cut. Enjoy.

And lastly my favorite EDC at the moment. Whittles like a dream.

Didi you take that Cara-Cara flat to the stone? How does the edge hold up?

I have been curious in doing that myself and bought an FRN one just for the purpose. Have not got around to it yet.

Yeah some of them turned out pretty ugly. I usually rush them because I don't care about the looks, just want the edge thin. On friends knives I take my time.

It's held up really well. It's the second Cara Cara I've done it to. Cliff Stamp originally got me started reprofiling knives by saying I should try taking a Byrd knife flat to the stone, and these days my knife collection looks like this. :D
 
Nice thin grinds, I'm tempted to do the same to my Byrd.. did you go just far enough to remove the hollow ground? Also, it looks like there is a micro-bevel (?) what angle is that set at?

Nice to hear. I was a little leary of the 8CR13Mo rolling easily when re-profiled that thin. How does it do on harder materials...i.e. hardwoods,soft wire etc.

This video turned out pretty unimpressive really, but here's the Para whittling a stick.

TomCRX, what I do when reprofiling my edges is gradually take them thinner and thinner until they start to get tiny chips in the edge doing the most edge abusive cutting I normally do (Whittling seasoned hardwood using some light prying action to break off chunks of wood, cutting through thick plastic bottles and ties etc.). From there I grind the back bevel at a degree or two more obtuse an angle and then apply the microbevel.

The Cara Cara sharpened flat to the stone, eliminating the edge bevel from the factory, then applying a microbevel, has never chipped doing these tasks, meaning it would be safe for my particular uses to take it even thinner than flat to the stone. It wouldn't be time efficient for the little cutting ability it would gain compared to where it's at, so I leave it as is. Still cuts very well. If you'd like I can mail it to you and let you try it for a week.

Thanks for the offer Vivi. I would like that. I'll send you an e-mail with the details.
 
Do you always reprofile with a sanding belt? how long does it usually take? specifically the skyline and s30v knives and would a sanding belt be the same as sandpaper? I have some 80grit sandpaper and I'm thinking about reprofiling using it.
 
I've been using a DMT Extra Course stone for these knives. The Skyline takes much less time than an S30V knife to reprofile since the steel is less wear resistant. The type of reprofiling you intend to do factors in as well. Taking a flat saber ground knife flat to the stone is very time consuming, but thinning out a flat ground knife usually isn't so bad. The 80 grit sandpaper would work for the job regardless.

I haven't used a beltsander but I'd like to get one eventually.
