Re: I s’pose it’s what you get used to.

I guess it really is what you are used to. Any more and my most common carry is a small CRK Inkosi and a Native LW S110V. Sometimes I will carry a large Inkosi or my only Military (jade M4). But I am used to a shorter blade, and I have caught myself (painfully) with the tip of the Military when I wa...

Re: Burned Edges....

It is very easy to form a burr with power equipment. If the burr is only straightened rather than removed by the final sharpening steps you are left with a weakened edge. I suspect this contributes more to observed issues with factory edges than does overheating, though I don't know how often either...

Re: Burnt Orange Rex 45 para 3

Plus the Rex 45 is run harder than the Hap40 was, maybe 3 points harder.

Re: Burnt Orange Rex 45 para 3

What's interesting is the GP knives in stock email notification was almost instantaneous. ..which worked for me cause I was on my phone. Similar to knivesplus for the Rex PM2 in that I got a "live" email in stock . Some retailers it seems use this feature responsibly. ..other not so much. Perhaps, ...

Re: First ever grail knife has been converted to MY knife

My wife gave me a knife, and I have been able to maintain that I have never spent as much on a knife as she has. Of course it was a Ray Laconico custom folder, and she doesn't know how many or how close to that price I have bought, but I can still say it.

Native LW CTS204P green FRN, please.
That would be my first choice too.
I vote for this as well. :D

Id buy this too. The Native LW is my favorite model so any new steel is pretty much a must buy for me.
Add me to this list.

Re: Burnt Orange Rex 45

Look at Crucible's data sheets. They show M4 at 65 is noticeably tougher than Rex 45 at 67, and also a little more wear resistant. Spyderco doesn't run M4 at 65 (as far as I know, except an early run of Gayle Bradleys), so the wear resistance is probably pretty close. An older one: https://www.carte...

Re: Best Sharpening Resources?

Michael's videos are very impressive, but I get plenty sharp edges without going to the great lengths he does. I do not go for such refinement so that makes a difference. In fact, most of the time I only use one stone - EF DMT - unless the edge is pretty dull or needs restoration. Having said that, ...

Re: Maximizing Edge Retention – What CATRA Reveals about the Optimum Edge

Buck's testing many years ago proved this - 420HC lasted longer than 440C and BG-42 when it had a lower edge angle. They then changed the angle of their knives and called it Edge 2000.

Re: Maximizing Edge Retention – What CATRA Reveals about the Optimum Edge

It is no surprise that edge angle is by far the most important factor. Doesn't CATRA actually measure force to cut (a given force cuts a measured number of cards cut)? Then actual apex sharpness is a secondary contributing factor, as seen by the actual apex thickness on the micrographs. Perhaps bett...

Re: Brown S35VN PM2s are back in stock at Knifecenter.

And it looks like a brown Para 3 S35VN is coming out soon.

The brown looks better in person than in the pictures on the dealer sites.

Just went to preorder through Knifecenter at $188.00 showing discontinued / out of stock now. I thought this was around $140-50 originally?

That was the Military you ordered. The PM2 and Para 3 are in the range you thought or less.

Maxamet has a lot of tungsten, and tungsten is very dense, about the same density as gold, 70% more dense than lead.

Re: Sharpening high vanadium steels

Even Michael Christy's test for carbide tearout with S110V left it hanging because he used ceramic for at least one step late in the sharpening before finishing with extremely fine diamond strops. The stropping probably did not affect the results much. (Not to knock Michael's work, I find it interes...

Re: Sharpening high vanadium steels

It may be academic, but unless you have done testing with both diamond and other media you don't really know. That would include almost everyone, myself included. In recent years I have only used diamonds; others commenting here have only (or almost exclusively) used SiC or ceramic, so for the most ...

Doesn't matter is different from myth. The pictures, unless doctored by multiple people, show it to be real. The doesn't matter part is what matters to me and others.

Re: Sharpening high vanadium steels

Again, a refined edge is not the question. The question is whether the potential loss of carbides at the apex makes a difference in performance, not sharpness - how long that refined edge lasts. I am not arguing either way. I am asking the question. The loss of carbides is a myth. So those pictures...

Re: Sharpening high vanadium steels

As I said, draw your own conclusions and balance them against your own experience. The micrographs tell a story, but what is the correct interpretation? How much impact does it have in real life? Real life, I would say ZERO. All of those steels can an will take an edge way beyond the point that any...
