    Re gardening 35vn

    HT 410 steel for liners?

    I have preliminary results: I hardened 410 FIRST and was able to drill reasonably well, tap threads, slice and bend the lock lug. The lug kept it's springiness. Now this was .040" thick stuff(what I will use for pocket clips), so we will see how .050" and .060" works for me.

    * Question not answered......... but now I do know: 1. Harden 410 steel @ 1800 deg for 5 min. Temper @ 750 deg, for two hours, two times. You shoot for 45 to 38 RC. 2. I did my own testing, expecting to fail. I hardened 410 too the above formula and I think I can handle it by...

    Steel liners question

    LINER LOCK: Plan to use 410 SS for liners. I've always used titanium in the past. 1. Do you harden first, before drilling, slicing, bending. 2. Do you do the above before hardning.......note 410 is quite soft and can get out of "flat"

    Wicked Edge Question

    Looking for something that is fool proof. I have a problem of not getting the bevels the same on both sides when reprofiling, especially the last inch of the tip. I have an Edge Pro and have used it for years, but too often the problem occurs. Clearily I'm not a great knife sharpener. Is the...

    Ordered some in .100" thick. I have the HT info from the maker but surely there is good advice from those who have actually HT the stuff. ie : What would be the best hardness for a folder blade of that thickness? What is your advice on the HT?
