My knife builds

[BBob]

The steel is NitroV stainless with cryo treatment as part of the heat treat process

First off another cool knife! On to the question. Do you notice a difference with the cryo treated steel as opposed to non-cryo as far as grinding, forming the blade?

Thanks mate

I would love to say they I can tell the difference, but the reality is that I cant tell any difference. I started getting the cryo done this year, and it seems to be worth it to get the best out of the stainless steels that I use. But even that is difficult to quantify, aside from differences with Rockwell testing. Much harder to evaluate in performance, but indications are better edge holding which is the theoretical advantage of cryo.

I profile out my blade shapes and drill all the holes pre-heat treat. Then I do all the other work like grinding bevels and tapering tangs post heat treat. I have settled on a grit progression where I do most of my grinding with a ceramic 36 or 50 grit belt, then when the edge is a little under one millimetre, I switch to a ceramic 80 grit belt to start cleaning up the scratches. when I get to .5mm or even .4mm, I switch to a 120 grit ceramic belt. The coarse belt really rips through the steel and I cant really tell anything across the different steels, even the very abrasion resistant steels like Magnacut or 3V feel about the same. I can see it with the super steels in hand sanding, but not grinding.

This is a bit of a design tweak on a knife I have made once before. The blade shape gives it a good drop point and also plenty of belly, so hopefully a good all round field prep knife.

The steel is 2.5mm N690 stainless. I have taken the edge down to 0.2mm, and the point has a good taper on it, so it should slice well, and also poke into game easily. The handle is green G10, with orange G10 liners & pins.

Those larger bellies do have a place in the cutting world. I've noticed a lot of your knives, really nice work.

These are a couple more willow leaf knives I finished last week. As with the last one I posted, the steel is 2.5mm N690 stainless. As with the last one, I have taken the edge down to 0.2mm, and the point has a good taper on it, so it should slice well, and also be pretty pointy. Both have handles in G10, with G10 liners & pins. One of the last things I did was make kydex sheaths for these right before I went to the show.

Yep, that orange one is a good design from you.
