JPH Posted October 22, 2008 Share Posted October 22, 2008 Those are rather spiffy...what did you harden them in? I get about Rc 50 on mine using caustic soda (lye) brine.....I don't even temper them at that low a hardness...Never had one break... Looks good...I really like the lines on the top one...

KYBOY Posted October 22, 2008 Author Share Posted October 22, 2008 Thanks.I kinda like the top one better myself. The bottom one I just kinda went with the flow, no real plan..LOL..I just quenched in water.No temper.What formula do you use for your brine? If you dont mind me asking??

JPH Posted October 22, 2008 Share Posted October 22, 2008 KB: I simply use my bluing salts that are a satuate solution of sodium hydroxide (lye) and ammonium nitrate (ferltilzer). I use it hot (290 D F) and quench in that... Like I said at that low a hardness I see no reason to draw any temper. They will never cut like a "solid" (>50 pt C) carbon steel will but at 50 Rc, they do hold an OK edge...at least for me they do...
