I have an old 1/42 Norton and they are better than the 1/30 by a big margin.

You can do so much with them. All you need other than that to make knives is a
angle grinder with a cut off wheel and a Dremel. A small drill press is helpful as well.

If you want to get started just sharpening knives ,try some old rusty garage sale ones. It might also help you understand how blade geometry works to use a Lansky sharpening system. I have been using my Norton for a couple years and I am still a bit leery of how darn fast I can screw up a edge. It is like using a bench stone except vertical rather than horizontal and at warp speed.

Now that I got you good and worried my next piece of advice is to be smooth and confident in your movements. It will take some time to get used to the tiny adjustments. You might even try taking some old lawnmower blades and trying to put nice smooth edges on them.

Take your time. You have the right equipment and now with a little practice you will be able to put a wicked edge on anything. The most important thing though is to really understand edge geometry and how it works and which type of edges are good for what purpose.
