Black and green polishing compounds
Round diamond burr rotary tool bit
I never tried this before so wish me luck. It either works or I spent a lot of time cutting out a knife and will ruin it. First I gathered up some poster board, a pencil, a utility knife, painters tape and a set of compasses.
Step 1: Getting started
First. I outlined the knife blade on a piece of poster board. Then using a utility knife partially cut the outline of the knife.
Step 2: Follow the line
Second, I followed the outline of the knife with the needle point allowing the lead to mark on the inside of outline. I used the compasses opened about a 1/4".
Step 3: Cut it out!
Third I finished cutting out the outline of the knife and then cut out the middle section using the utility knife. This gives you a stencil to follow to engrave the knife blade
Step 5: Slow scratch
Once satisfied remove the stencil and re-polish the blade using black and green polishing compounds and you are finished. I used my drill press with polishing wheels to do this.
Step 6: Not bad, if I do say so myself
I don't think it turned out to bad. The knife has an overall length of 11" with a 6 3/4" blade. It is made from 1/8" industrial hardened steel from a 17 1/2" saw mill blade. The handle is made from oak burl salvaged from a wooden pallet with brass pins. The handle was sanded to 800 grit and treated with a 4:1 mixture of mineral oil and bees wax.
