Today I MADE

thankyou sand surfer, and your right once it starts to fall into place it gets so much easier, and you get to know the heat by the colour of the metal, I would love some of the gear they had in the Kalgoorlie shop where I did the course, but I have learned to use the basic gear I have.

Mono steel blades were relatively easy, but the Go Mai style were/are a real challenge, putting three different types of metal together in a forge and making it come out how you want it, Go Mai stands for 5 layers, which in this case is a center core of 1095 or 1084 high carbon streel, then a layer each side of that which is 0.1mm Nickel sheet or can be 0.1mm Copper sheet, depends on the effect you want, then a cladding outside layer each side of that can be mild steel or Damascus pattern welded steel or Wrought Iron, are just some.

Then the handles, the Octagon Chefs style Japanese ones, which were quite hard to do for quite awhile, on the gear I have, but with some trial and error it finally came together also, and the timber used is just up to your imagination of what might look nice.

A basic single burner gas forge an anvil and hammer and a modified grinder to be a belt sander and make it all work

Most of all enjoy doing what your doing

I finished this small kitchen/Chefs knife today, Go Mai construction blade, 135mm long and the handle is Mulga which I brought home from WA, and a copper spacer, all finished with beeswax and baby oil mix 50/50 warmed and polished in.

The blade is forged so the Nickel sheet is fused to the layers of steel, hammered out on anvil to a suitable width and length, then the blade profile is cut to shape, course sanded with 40 grit to thin it down so the spine is 3mm thick and flat from spine to where the cutting edge will be.

Then the blade is heated and cooled a few times (thermo cycled) and then heated and oil quenched, and then tempered in the oven at 200 deg c for two hours.

Then hours and hours of belt sanding, starting at 40 grit, and working up through the grits, 80 to 120 to 240 to 400, to get the bevels from the cutting edge to the spine, and then had sanding with 600 grit to finish it off.

Go Mai is 5 layers, a center core of 1095 high carbon, then a 0.1mm Nickel sheet each side of the core, and then Mild steel cladding on the outside, all sanded to 600 grit and etched in Ferric Chloride, and then re-etched in Coffee for a couple of hours, rinsed and dried and also treated with the beeswax and baby oil mix warmed up.

the paring knife in the above post I sold so I made another one today

Blade construction is Go Mai center core is 1084 high carbon steel then 0.1mm Nickel sheet then Wrought Iron cladding.

The handle is rosewood and ebony with a copper spacer



I also made up another handle from scratch to fit on another knife that was missing a handle

This handle is Red Gum and Ebony with a brass spacer, Octagonal shaped and finished in Beeswax and baby oil mix 50/50
