Cutting a freestanding hair with S90v

Just curious, but was this just an exercise in seeing how sharp you could get your knife, or do you use such an edge to cut things.

If you use that edge to cut things, I would be interested to know what you are cutting and how long the edge lasts.

A knife can be made very sharp, but depending on what the knife is being used for, a super-sharp edge might not last very long.

Creating a "hair-splitting" edge is fine if one is going to use their knife to split hairs, but such an edge won't last very long if say, a person were going to spend the day cutting roofing paper.

If this was just an exercise to see how sharp you could get your knife, there's certainly nothing wrong with that. There's more than one way to enjoy our knives. :)
 
Very good point killgar.
I have a few strops sitting around collecting dust, i uses to strop to the point I can hit my hair and it'll pop, which I'd difficult with my thick hair. But cut something once and it's no longer u per sharp. It took a LONG time to get there too.
I can't justify the time spent.
On a 8000 grit stone, it's plenty sharp (slicing circles in wax paper) and lasts quite a bit.

I use my knives for carving various wood and light utilities.

I don't sharpen my axes this sharp.

I like really sharp knives and I'm on an endless quest to make them as sharp as possible

Well for me this level started as an experiment kinda...I was told by a work sharp hater I could never achieve such an edge using it...so I had to prove em wrong, and thou through use the knife has lost the edge in the video it'll still whittle a hair. So it's actually holding a very sharp edge fairly well...

But I do like a very sharp knife on my carving knives as well.
 
I am the same way. I do not use it at all for anything other than the quest or showing off. It's just fun to see where your limits are and then trying to take then further as you learn more. After spending nearly 7 hours on one edge, I am way to scared to actually use it cause of how much time I spent in it to have it dissappear in a matter of seconds...lol hmmm
..7 hours gone in 2 seconds...that sucks

Yea I know I was just given you a hard time.. I imagine it's similar to s110v...for general sharpening its fine but any major reprofiling it sux...I recently acquired a used pm2 in s110v that had been badly sharpened...It was sharp but ugly uneven bevels that needed fixed...I took the easy route and just sent it to R.E.K. to have it reprofiled. Lol
 
Haha...got ya.
Yea, those cpm's do not like the super small cbn's either when it comes to mirror polishing goes.
 
In fact, I have a 140 grit kme stone I am using for a 14 dps repro on the elmax right now and it was so frustrating I had to order a 100 grit to complete the job

That hilarious, as a knife sharpener, I refuse to pay someone to sharpen my Knives, but in the future, with having kids and a lack of time. I'd truly be able to appreciate the time not spenpt sharpening knives. Let someone else slave away for a change XD

Yea I know what you mean, I had a pm2 s110v before this one that was factory new...It took me forever to just even out the factory bevel and drop it to 34° inclusive... I wasn't even trying to put the work into the used ones edge.Lol

It'll be the first knife I've ever sent off for sharpening.

I edc that edge, 12.5dps at 160,000+, a year later and its still just as sharp, i touch up up occasionally on a 0.1u strop with poly diamond. But its never really needed it.

That edge must be ground fairly thin, that bevel is quite small considering it being 12.5°.
