I may be misremembering this but I want to say I've read that 15N20 is good knife steel since you don't want to use a steel for pattern welding that is less than ideal by itself. That said I have done some searching for more information about using 15N20 for knives but I'm not seeing much that isn't people talking in circles. My curiosity stems from a guy at work that said he might be interested in a knife but only if it's a folder. I know I could use some of the 1084 I use but think that the 15N20 would be a little more corrosion resistant which I imagine would be great for a knife that's in your pocket all day. I know I could use stainless if I'm that worried about corrosion but don't feel like it would be a wise investment to buy a piece of stainless for a single pocket knife. Feel free to tell me I'm just being a little crazy and that I should be less worried or whatever else you think I need to hear.

I think 15N20 is great knife steel, and I've done some light, kitchen stuff in it.  The problem stems from not being able to get it in thicker sections.  I've seen it in 0.100 but no thicker.  If I could get it in .250, it might become my go to steel.  I don't know that it's much more stain resistant than 1075, but that might be worth a test.

I just got some in my last steel order that was 1/8" thick. I know that's not thick enough for me to forge it well but it's plenty thick enough for a pocket knife if I don't mess it up. I just knew I don't see much about using it anywhere except for pattern welding. I don't know how stain resistant it really is, I just assumed (shame on me) that the higher nickel content would make a difference as compared to the other steels I have on hand.

I would not forge that pocket knife blade, I would go stock removal. Unless you have access to a surface grinder.

I would love to be able to use a surface grinder but I don't know of any I could use. Hopefully in the next week I'll be able to finish my 2x72 and finish up a few of the knives I have laying around. 

I think I will give this project a shot and see what comes of it. Thank you for the help, Geoff and Joshua.

I had some 15n20 lying around and used it to make this because it was the right thickness:

Unfortunately, I haven't had much time to field test it, but it seems to do the job just fine. A word of advice: when you drill holes in it, it has a tendency to work harden if you don't "peck" at it and just try to go through. It got to a point where I had to change the location of a pin hole in the springs because my first attempt had become impossible to cut through (brand new cobalt drill bit with oil and still screeching). I also kind to like the idea of using 15n20 for novelty, since you don't see it a lot on its own even though it can still make a good blade.

Sorry for the delay, Aiden, I appreciate the tip on drilling. That's a good looking knife and isn't too terribly far from the direction I'm going. 

So far all I've managed to do is we have come to an agreement that a two blade knife similar to the Barlow style is a good knife. Things have been kind of crazy lately so I haven't managed to do any design for it yet but hope to get this moving soon.

The biggest hold up on this project is trying to get my belt grinder running. I got everything I needed just to go to put it together and find out I need more parts. :(

15n20 is good stuff, similar to 1080. High carbon, low alloy with 2% nickel. But it's not usually available thicker than 1/8" in flat stock. 52100 is similar, but with chromium instead of nickel. 

If you like 15n20 but want thicker stock, try L6.
