Currently working on a bowie - this is the first knife I've done that is actually turning out to be something I want to keep (I've made about three already, but none of them impressed me enough to finish them all the way). Anyway, I'm having trouble with the bevels. All I have to work with right now is an angle grinder, and my hand isn't steady enough yet to create perfectly straight bevel lines. I got them close to what I wanted, then tried to straighten them out the rest of the way with a hand file. Unfortunately, while I did get them straight, I also managed to sort of round off and smooth them down in the process. There's no sharp ridge anymore - it's just like... sort of a gentle bump I guess.
Do I just need to practice more and get the bevels straight with the grinder? Or is there something I could do better with the hand file? Also, how can I fix this? I was just going to hit it with the grinder again - will that work?
Thanks for the help everyone.

I find a belt sander is best for keeping bevels crisp once you have set your main geometry and done your main material removal with a grinder. Specifically the belt sander can ensure your lines stay relatively straight as long as you're not moving the plane of the blade around.

A file is actually one of the best things you can use to get perfect ridges. Look up and build what's called a "filing jig." They are cheap, simple, and amazing little tools. Perfect strokes every single time.

Thanks Verity. Belt grinder... mmm... I really need to invest in one then. I've been trying to get by with what I have right now, until I get the cash I need, but I'm going to have to stop putting it off eventually I suppose.

Yeah, they are insanely easy to make. And if you're ingenuitive enough, you can make them out of just about anything.

Once you get a belt grinder, which you will need if you're serious about making blades, I'd suggest getting a bubble jig kit from Fred Rowe. I just got one, and tried it out yesterday. All I can say is I should've got it a year ago... bubblejig.com/

Here's the first flat grind I've done using the bubble jig, just yesterday. Again, I should've got the jig a year ago when I was starting out...
