310---410---420 Ss?

[Robert Hankins]

Of these three which makes the best material (Easy to use is good) for folder liners???

310 is an austenitic stainless which can't be hardened by heat treat, 410 is a hardenable grade as are 420J2 [low carbon] and 420HC[moderate carbon]. 420J2 would be ok for plain liners but if it's a liner lock knife I'd use 420HC.Both 420s are used for low cost blades.
