Try to punch on the middle line of your blade for all your pins to get aligned. Drill a pilot hole with a small drilling bit. Don't forget to lubricate the bit with oil or WD40 and go slow to not break it.

Then, drill the holes to the final size. The ones near the tip of the blade are the smallest ones, for the pins. The last one will be used for the brass tube. Just take your time and lubricate the drill bit.

Now, you will give your blade its final shape. You can use many tools 2x72", belt sander, grinder, etc Giving your blade the required bevel by hand allows you to go slow, don't make any mistake and get bevels with the same angle on each side of the blade.
