at first, put your old tool inside an oven (900degree celsius). after the tool is all colour red, take it off from the oven and let it become cold inside of a bowl full of sand. this way of cooling is slower than atmosphere cooling, so the tool become soft again before shaping.
Step 2: Start Shaping
start shaping your knife by the shape you want. in my knife at first i drawed into paper and sticked into with some tape. by this way i took a rotatory tool with a disc of stone and shape it.
Step 3: Finishing Grip And Starting With Sharp
Step 4: Temple
in this step , return the steel in the oven and let it become warm until 1200degree celcius, when its all red, let it cool in oil. now it has become hard again . before temple drill grip holes
Step 5: Pulish
take a paper sand and start pulishing the sharp because in temple has become rough
Step 6: Stick Grip
stick the grip using epoxy and start sandering it with sandpaper until its has de shape you want to.
Step 7: Pop Grip
pop the grip with a hammer
Step 8: Time To Eat
