You would be well to the wise to listen to the advise you have asked for.
You were given the way for better annealing - heat to non-magnetic; cool until it doesn't glow; quench in canola oil.
If you had done this, you would be getting a lot better results.
Also, get a
high tension hacksaw and some
lenox (or other brand) Bi-metal blades. They sell both of these at Home Depot/Lowe's/etc. The High Tension saw frame and a pack of blades will cost about $30. The handle will outlive you, and the pack of blades should last years. When using a metal cutting saw, cut the steel on the down stroke only and don't "saw" back and forth ( lift the pressure on the return stroke). A high tension hacksaw will cut many times better than a regular hacksaw.
When drilling holes in steel, the drill can harden the metal as it drills the hole. Slow speed and lubrication are the key to good holes.
Almost any heat source is better than sticking the steel in a fire pit. You can make the steel softer, harder, or ruined by doing that. Try and see if you can make a two-brick forge, or maybe talk your folks into buying you one of the Atlas Mini Forges ( manufactured by Zaph on this forum):

If the steel from the fire is messed up, I would trace your pattern on a new piece and try cutting it out again with the proper hacksaw type and blade. I'll bet it cuts just fine.
At age 15 it is hard not to rush things, but knife making isn't something you do in a hurry. Take your time, read the stickies ( especially the "Instructions for making a knife" one), and post your questions here. There are a lot of great guys here who will offer help and advise. Maybe one of the smiths in the San Jose area will offer you and your parent a visit to their shop and help you profile that knife.
Here is an old thread about finding a maker in the San Jose area. There are some really nice guys within a short distance of you. An email may get you off to a great start.

I would also suggest you check out NCKCA - the makers will be there.

Does anyone know if BAKCA is still together?
