Is there a tool that you have started using that you now find essential?
A few months ago I bought a scriber. I've had ordinary metal-working scribers before, but this one is produced by Bare-Metal and is specifically designed for scribing panel lines.
Now that I'm used to it, I really cannot imagine ever having managed without it. Applying filler to large areas used to give me major cause for concern because I was never certain that I could restore panel lines to their former glory using an ordinary scriber or a needle. But the BM scriber makes it so easy! I'm even considering building very old kits that have hideous raised panel lines, because now I can scribe my own with a high degree of confidence. I love my scriber!
So what is *your* essential tool?
