I know this is supposed to go in the knifemakers discussion forum, but I tried twice and it would not let me post. So if the mods could move this thread that would be great.

To no ones surprise I made a drop point hunter in 440c. I have sunk 40 hours into it using files, hacksaws a hand drill and a dremel. It has been going along very smoothly and I am ready for heat treat. 40 hours might be a bit conservative.

To Mods, I can not seem to post anything more than this. It just keeps on loading.

To anyone interested please read the comments
 
So onto the heat treat. I plan on getting a bunch of charcoal, lighting it and blowing air at it with a hair dryer. then putting the blade blank in and testing if it is still magnetic periodically. once it does not attract the magnet I will dunk it in some corn oil then it will go into my oven at 400 for 1 hour, and will stay in there for another hour while the oven cools down.

Please if anything is wrong with what I am doing please inform me. I really don't want to screw up all my work on the second last stage.

Thanks in advance,
 
440c needs to be heated between 1850 and 1900. This is a pretty precise temp that you probably can't get with charcoal and a blower. Your best bet is to send it out for heat treatment or get some 1084 if you want to do it yourself. That is a good looking start to a knife so I would send it out.
 
Thanks For saving me the heart ache. I will do the smart thing and just send it out. Thanks for the recommendations.
 
I see a lot of random holes in the tang (which is good), but don't really see which ones would be used for the pins/rivets?????? Are you using pins?
