"HRC as advertised." Who is accurately listing HRC?

K Knives Switzerland has taken it to 64. I think Shawn might have, as well.

60-62 is a range a lot of people would be very happy with in production.

This has me itching to test my s90v Shaman. The s30v was 60.2 :)

Impressive and informative, as usual.

Even a toothbrush makes a formidable shank in the right hands.

I'd have to agree that if you don't use your knives it seems strange to worry about a few rc points. You don't need boutique heat treatments to pierce flesh with something pointy.

Daggers are illegal in Illinois. I have a few and cannot legally carry any of them.

When looking for a weapon, I look for nothing but the best. My life depends on it. When people carry firearms, they also debate about stopping power and what clothing the target happens to be wearing. Same principles apply to knives.

Daggers are in fact legal in Illinois (not including crazy Chicago laws), most knives (including autos, if you have a foid card) are legal as long as you aren't carrying them with the intent to harm (attack) others. Then they would be considered dangerous weapons, this can apply to anything, from a broken beer bottle, sub 3 inch knife all the way to a katana.

The only things that are illegal are brass knuckles and throwing stars if my memory serves. All the information is in this link.

s90v shaman is 59.5, pretty dang solid!

That's pretty low for s90v IMHO. But don't take that the wrong way. I'm actually a big fan of Spyderco's s90v as is. Great steel.

if i remember correctly crucible's recommended range is 56-59, so while I'm sure that custom makers can take this well into the 60s, on a hard-use knife like the shaman, I appreciate having at least the manufacturer-rated impact toughness.

59-60ish is normal for production blades in S90V.

I'm aware. S90v is more geared for performance though. If I was to buy a custom I'd prefer it higher.

60-61 is about the max for S90V even in customs depending on the batch and who is doing the heat treating.

S90V doesn't do well at the higher hardness, it gets pretty chippy… So 59-60ish is pretty solid...

S110V is MUCH better in that regard, can be taken to ~64...

That lines up with the numbers we have for Spyderco S90V in the HRC Database. Can I ask who tested it curlyhairedboy?

S90v 60+ is good stuff. But so is Spyderco's. Very well balanced.

I did not know that a FOID Card allowed you to carry a dagger! Going to have to renew my FOID Card.

What I was saying is you need your FOID for automatic knives. Anyone can carry a dagger.

Naperville, that is horrible. All you did was let them know you had a knife. They could have killed you otherwise. It's not illegal to walk down the road with a gun openly holstered on your hip (and shouldn't be, ANYWHERE, if you have a permit). Doing so simply lets people know you have it and they're a lot less likely to mess with you. You had a legal item and didn't attempt to harm anyone. Sorry to hear about that.

That pretty much sums it up. LTK and the people in his group are doing a huge service to the community.
No one is claiming HRC is everything. Like LTK said, you CAN have bad cut tests results with high hardness. But acting like HRC is irrelevant is beyond disingenuous. While Buck pretty much nails their HT on 420HC, there's no excuse for it outperforming ANY M390 in any blade.

Just for the records here on the Spyderco forum, it’s instructive to see how CollectorKnives followed up on LTK’s reporting low HRC Lionsteel knives with a 3rd party verification witnessed by the tester quoted by LTK, how this tester took down his Instagram account, and how LTK has yet to respond:
Production M390 - Expectation vs Reality?

if i remember correctly crucible's recommended range is 56-59, so while I'm sure that custom makers can take this well into the 60s, on a hard-use knife like the shaman, I appreciate having at least the manufacturer-rated impact toughness.

So for S90V Crucible’s HRC recommendation matters (for improved toughness), but for CPM-20CV it doesn’t ?
