Knife project for a friend with the same interest in serama - part 1

 The knife was made using stock removal technique. Shaped till closest to the final dimension and ready for heat treatment.
 DIY furnace that i used for all my knife projects using metal pipe, normal construction cement that was bought at a local hardware store mixed with sands and ashes.
An old vacuum cleaner use as blower.

Charcoal fire from this furnace is hot enough to heat the steel that i'm working to hot orange colour in less than a minute.

For this knife, the blade was normalize (the blade was heated to non-magnetic temperature then air cooled) two times . The blade then reheated to non-magnetic temperature and edge quenched in old motor oil.

 After quenched, cleaned and checked to make sure there are no cracking and major warping, the blade was tempered in electric oven for two hours at 200 degrees celcius to bring the edge hardness to about 61-62 HRC based on the heat treating table for DF2, the steel used for this blade.

Installing the fittings.
