Any suggestions on heat treating really thin, 0.049" stock in a 2 brick forge? On a whim I added an 18x1.5 piece of 0.049 thick 15b20 to an order from Sheffield*, thinking I'd try making a paring knife. I haven't used 15n20 but read here you can get good, if not ideal, results when doing a simple home ht like 1084. I've had good luck heat treating 1084 I'm my 2 brick forge, but never anything this thin overall. Should I just ht the blank prior to adding the bevel? I don't have a proper grinder (just a 1x30), so it's either filing before HT, or doing it all by sanding after HT. Any tips on keeping it straight or straightening it if it gets a little warped? Is it silly to even try something this thin? I've got enough to experiment a bit. *I emailed about aking about filling jigs and they offered one for cheap because of light rust, so I wanted to find a few things to add to the order at full cost. I was impressed - "light rust" was actually a bit overly dramatic, more of a light discoloration that a just a few moments on worn 1000 paper in a surface plate removed. It's a nicely made hardened steel guide, better than the one I had made.
