Sprint Para2 H1

Maybe not practical. Just looking to see what will spark some interest for the next dealer exclusive or sprint run PM2.
 
I thought that knives using Japanese steel had to be manufactured in Japan? Maybe I misunderstand things, but I think there is some Japanese manufacturing law that regulates some of that stuff.

All the knives I can think of that use Japanese steel are manufactured in Japan. Someone correct me if I'm wrong.
 
I actually would not be that interested in it. I have had no problem with knives rusting under normal conditions, and H1's edge-holding capabilities are not that great compared to S30V, and sprints usually have a "super steel" or at least a newer steel not in high production. It would not seem to fit the philosophy of the sprints imo. It would seem backwards to me, not to mention the already mentioned issues of making the rest of the knife as rust resistant as the blade. Outside of a more rust resistant knife is there anymore advantage I am missing? Also, can anyone provide a picture of a S30V (or any other SS version) PM2 with rust on it? If not, why bother?
 
I agree. I don't have much desire for H1. Doesn't hold an edge well and my one boat knife is all that I need.

They have H1 in Golden now. It had something to do with their new Coast Guard auto called the Autonomy.
 
I don't mind H1 as long as it's serrated. With that being said it's kinda a specific steel, however it is capable of excellent edge retention with serrations and doesn't rust so I'd say it has potential in a general use EDC knife.
 
I dig my Pacific SE, and having Yellow G10 and Serrations on a Para2 and then rust proof. Thats hard to beat in my book. You can take it anywhere with no worries. My Se Pacific is holding up very well for being a softer steel.
 
Just another tribute to my favorite knife design. That's pretty much all I'm after. Thanks for all the posts. Interesting to see everyone's take on it. I love this place.

If they have H1 in house, I guess they could do the liner, pivot bushings, screws, clip, etc. in H1. But I'm not sure how well that metal would work for those components. It's been many moon's since my tool making days. Way before CNC.

why can't it be FFG?

I think bright yellow G10 would get dirty very fast.

Look at the first few links

Best answer I believe:

It can be, but not on a commercial production scale. H-1 is not conventionally heat-treated. It is hardened by working it. It is cold rolled to a specific thickness and hardness, then cut into blanks. Grinding will further harden the steel. Flat grinding commercially is done one side at a time, so when the time comes to grind the other side, it is a lot harder than doing the first side. This leads to excessive tool wear and can lead to overheating of the steel. Hollow grinding is done on both side of the blade at the same time, so the work hardening will be even and so will the tool wear.

H-1 can be flat ground by alternating sides and cooling frequently, but that is too labor intensive to be cost effective for mass production.

H1 Military has been discussed before. I wouldn't mind a hollow ground H1 Para 2 with yellow G10 on ti liners and a full spyderedge, but the fact that the Para 2 is manufactured in Golden and H1 is produced in Japan apparently makes things difficult.

My Pacific Salt is the only knife I would ever take to the beach. I don't have a PM2 but I'm sure it would rust if i used it how I use my Pacific Salt.

Even the Pacific Salt got all rusted up on the H1 logo! (From my understanding, from the tiny remains of tool metal left in the logo when it was etched in)
 
No. From what I've experienced H1 has about the same edge retention as 440HC. Unless it's in serrated form, even then it's scratches easier then 420j2.
