[Bryn-gwlad] spring stainless (410)...interesting factoid!

[EW Brown]

I was looking into knife making again, a hobby I delve into 
periodically, and I bumped into this
explanation why to use 410 for certain hig durability knife part(and 
thus armor) instead of a more commonly
know carbon stainless like 440c...

Since I'd been wondering exactly that question i thought others might be 
interested in the answer.

We looked the world over for the very best liner and spring making 
steel. Through trial and testing, we chose 410 stainless steel.
The basis of our conclusion was that 410 does not build-up or retain 
stress like many other stainless steels.
We have tested this steel on a spring bending jig for 50,000.00 cycles.
After the successful test, it still had room to make another 50,000.00 
cycles before the steel broke.
That makes for great spring steel! Our 410 steel is made in America and 
is provided in the annealed state, which makes it easy to machine and 
shape.
This is very important when you're working with it to shape it to your 
desired design.
