And pictures in these threads. A loupe probably does not have enough magnification to see it.

Re: Maintaining pm 2 s110v edge with sharp maker

Corners are faster, but more likely to raise a significant bur. I guess I am different from a number of you folks. I try to avoid forming a bur, sharpening evenly from side to side, bringing the apex up to sharpness with a minimal bur if any at all.

Re: Carpet vs. VG10/S110V

Maybe there is a difference but you surpassed the capability of both of them in this test. If you had stopped earlier you might have seen the difference. Old carpet is notoriously hard on edges.

Re: 52100 vs other tool steels

A forced patina on my M4 has noticeably reduced corrosion.

Re: REX 45 Military In Stock!

Mine arrived. Good centering, lockup, and plenty sharp. But boy I wish they would grind the edge thinner - 0.027-0.028" behind the edge. As soon as I saw the wide bevels I knew that was the case. Plus uneven near the tip. The thick edge takes away some of the benefit of the properties of this steel.

I don't think all the shops are adding tax. Bladeops did not, and the other day when I went almost through checkout at BHQ they did not.

Re: REX 45 Military In Stock!

I had email notifications requested from three places so far that have had this Millie but I received none. This has happened before, so I don't rely on them. The only place that has ever sent a useful, real-time notification was K Plus.

Bladeops had some for a few minutes, so with BHQ getting a few it looks like the mail arrived in Utah.

Re: REX 45 Military In Stock!

I’m willing to accept a little maintenance in exchange for what I perceive as outstanding performance. This is where I have ended up. I have been a mostly stainless person for a long time because it is often wet and humid where I live. Then I got some M4. I love the edge it takes, and holds. I also...

Re: Steels: Extreme Edge Strength

I am beginning to think that many steels have sufficient toughness for normal use in folders, and that in the end the edge strength (with hardness as a proxy) makes the difference in how much damage they take.

Re: I need help/advice Sharpening M390

In the absence of coarse rods, you can clip sandpaper to the rods you have for quicker stock removal, then use the rods alone when you get to the apex.

Re: New 20CV Para 2!!!

I am not positive but it sounds like Bohler may have the more refined processing of the three with possible finer grain. In the end heat treatment and edge geometry will make a bigger difference than steel differences though. I think Carpenter has the finest grain. But yes, heat treat and geometry ...

Larrin, you have probably seen these, but - there are a couple of rankings made by the steel manufacturers, though perhaps a bit dated. This one is the most comprehensive.

Re: Guide to the Best Knife Steel

Good as a general guide, though not necessarily strictly accurate. Many steels are listed with better corrosion resistance than S110V, but that is not true.
