Not another one... knife that is :)
KHalverson:
very nice!
bare bones no frills cutter
just the way im startin to like em for myself
0-1 is some good stuff when heat treated and tempered properly
takes a wicked edge and holds it thru quite a bit of abuse

Cardboard_Duck:
Thanks guys, I'm starting to like knives more than bows.... almost.
Kevin, this is how I did this one-
Normalized, brought it up past critical three times only letting it cool to about 500 between each one and then it cool to room temp.
HT'd, I brought it up to critical and quenched three times and then tempered at 400 for two - two hour cycles. I don't know the RC but all of my files skate on it. It took and so far is keeping a nice edge :)
KHalverson:
for normalization and grain reduction and you using 3 reducing heat cycles
wow :o if the file still skates after 2 temper cycles @ 400 f thats still hard 60 + rc
was it a bear to sharpen?
Cardboard_Duck:
It took a LONG time to get a nice edge on it, even with using worksharp sharpener. I used it quite a bit today with no noticeable loss in sharpness. I don't know if reducing heat cycles is what I did, it was more like three HTing cycles. All of them were up to critical and then quenched. I'm still learning this stuff so I might not know what I am talking about :)
KHalverson:
did ya edge quench or full quench the blade?
any warping?
a reducing heat normalization involves taking the blade to 1 color past critical and allowing to cool to 900 f +or -
second heat taking to critical heat only let cool to 900 +-
third heat taking to just barelly where a magnet sticks and allow to cool to room temp
do you have the $50 knife shop book?
