What is Delta 3V? I made a loooong video.

Excellent video!

Thanks for taking the time to do that video! Very informative on multiple fronts. I am curious though where your version of D2 would fit into the mix. I have a D2 version of the EDC 1 that I am pretty fond of and it seems to get very sharp (it was in fact the sharpest of the knives I have ever received from you and that is saying a lot) and holds its edge for a long time. But, I don't cut on bolts...

Nice job, well explained.
It would have been nice to show a diagram with the hardening humps at the beginning.

Lol.

Watched this today.The delta heat protocol was very well explained and it was some interesting viewing, now back to watching the Euros football.

Really great video - thank you for sharing! Nathan, you definitely have a knack for concisely explaining complex and often convoluted topics, and how the theory plays out in the real world.

I need to watch this a second time. Maybe with just the sound on. I go so distracted by the cutting I wasn't listening.

That was an excellent video. Very informative. Thank you!

Thank you for the video. I watched most of it and I have a question that I don’t think you answered. I understand the standard lower bound of tempering temperature recommended for CPM 3V is about 950 F. How much lower is the low temperature temper used in D3V?

The reason I ask is I wonder about using this knife as a camping knife for cutting hot foods. My research has led me to believe that a blade‘s heat treatment can be damaged if it is heated above its tempering temperature.

The heat treat of a blade will be damaged if it is heated above its tempering temperature even for a moment.

The boiling point of water is 212°

If there is any water in your food at all, touching it with any knife is not going to damage that knife's heat treat. Knives are not tempered lower than 212. Mine is over twice that.

The boiling point of water is 212° at sea level. YMMV

Smart ass.

Hmmm...so it looks like steam cleaning with IP steam might be ok at just a smidge over 400° but HP steam cleaning is a definite no-no

Evaporator?

Evaporator?

Heat Recovery Steam Generator...fancy name for a boiler on the back end of a gas turbine.

Some evaporators use a hotwell. That is what me think it. I see your pics with the HMI in the background. I design similar control systems for the food and dairy industry.

wait wait wait a second……. So if I use my knife for roasting marshmallows or for a kebab I will ruin the heat treat?

I need a long pointy skewer, maybe CPK could make a titanium heavy duty field skewer 3-4 feet long?

What is this. I don't even
