New Steels - 80CRV2 and 8670

Reads well to me.

Driftwood typically has a residue of sand on it, in it's cracks, textures, holes and hollows. Truly, a test for edge stability to cut against the fine, hard minerals that make up sand.

Somewhat similar to how most cardboard, having dirt in it's matrix, can dull some edges easily.

We also do some ultimate edge testing here at Pops. We cut open boxes of belts and abrasives. This cardboard is completely infused with ceramic grit material. Hell on an edge. I've been using Fiddleback knives for this task since Feb of 2019 and it really gives you an idea of what an edge can put up with.

And later on when it's time for maintenance, an opportunity to understand the ability of the edge and steel to respond to sharpening.

Hi guys. I know y'all have noticed the knives we've been putting out in 80CRV2, and there will be a few other steels we're going to try as well. Thought I'd drop a note here about the steels and why I decided to give them a shot.

A lot of the why is simple convenience. We carry these steels at Pops, so its just a matter of grabbing a bar and giving it a shot. A lot of it has to do with Joey, who is always trying new stuff and is really passionate about metalurgy.

The 80CRV2 was appealing to me because of its toughness. Its bombproof. Our local buddy Kevin S. who makes knives and shops at Pops a lot (thanks Kevin) really got 80CRV2 stuck in my head. Kevin has arms bigger than both my thighs together. He had a blade warp and decided to break it to see the grain. He put it in a vise, used a pipe for leverage, and didn't have the strength to break the 5/32 blade. Hmmmmnm. I couldn't get the picture out of my head. Plus Joey... I really like working the stuff, and even though it will/does rust, it is a very good knife steel.

Now Pops has picked up a good source of 8670. I've noticed a lot of makers use this carbon steel including Don Hanson. I'm intrugued. We got the stuff in on Tuesday. Joey and I are making test blades to beat up in the side yard here. (I'm making a Leuku from 5/32.) Its very tough at very high hardnesses. We're getting rc63 (tested) out of quench and are hoping to temper to rc61 and still have a tough blade. I'll make sure we post pics of the testing fun. If I like what happens with that Leuku, I'll be making a few knives out of that as well.

There are others I may try out too. We have 15N20 in the shop now as well and I'm hearing a lot of great stuff about it AND its stainless, so I may give it a shot soon.

Still love A2. The one on my hip today is an A2 knife. (A dud with bone handles and tiffany blue liners.) Its been passing the Pops Knife Supply test with flying colors. Pops is hard on an edge because we open lots of bosxes that are contaminated with the abrasives inside them. Its actually been a very useful testing ground for the knives. Convenient.

I may start putting out a few in CPM S35VN as well. I have a production Runt on the shelves in the belt storage area, and that stuff is amazing at the edge.

Little update. More to come. You can see the steels we carry at www.popsknifesupplies.com . There are quite a few nowadays, thanks to Joey.

Are you guys still planning on playing around with the stainless steels mentioned above, more AEB-L, CPM 154 or others such as M390, CPM 20CV, etc?
