Bigmon, Rio Grande sells various assortments of jewelers saw blades, and it may be to your benefit to get one of those. Whatever blades you get, buy several dozen.
They are extremely handy for almost any metal cutting task, and smaller wood projects as well. Generally, I use 2/0 blades - in fact cut most of the 4130 steel for several airplanes with that size. But now I also use Size 0, 3, and 4. Cutting is done vertically, for the most part. Just move your hand down to saw, with a wee bit of forward pressure. ANY side pressure will snap the blade.
These blades are very sharp, so do not interpose any part of your digits to the cut line. Lost track of how many cuts I have gotten, but at least for the past 15 years or so, the total is Zero! But I had to learn the hard way. A 2/0 blade will fit easily in a 1/16" hole. Or a 1/32" if you are so inclined and can drill with that size....
