Blade not straight
After filing the bevel I have noticed there is a slight curve to it especially near the tip. Would it be acceptable to heat treat it and then fix this with a grinder when I am able to purchase one? Currently the only tools I have to fix this are an angle grinder which I am not very proficient with, a file and my forge and a hammer. I can try to post a link to a pic in a few minutes

Generally you want to leave some material on for the heat treat. If there is a warp in the blade just from the bevels not being equal the blade will likely warp even more. A short blade isn't going to be as big a problem as longer ones. So to answer your question, yes you can but be prepared for the possibility of the blade to warping.

Get yourself a piece of angle iron and a couple of C clamps. Find where that curve begins in the blade and put the convex side of the blade up against the angle iron with a penny under that spot and clamp the blade with just enough force to counter bend the blade just a little. Then put the blade back into the oven for another tempering cycle. Allow the blade to cool before unclamping That may work for you without having to repeat the whole heat treating cycle to forge straighten it. If you do have to forge straighten it then make sure that you normalize the blade before you quench again. Also be aware that re-heat treating and hardening a blade that has finished edge can have it's own problems with warping though it's not impossible to do.

Fixing it before you do the heat treat is going to be easiest .. you are only going to make the steel harder with heat treating. Next blade, don't grind/file so close to finish before you heat treat, gives you a bit more wiggle room on final lines.
