I am a longtime woodworker and have used both extensively. I have a top of the line RBI Hawk scroll saw and while it will cut wood up to 2" very easily, they just are not made for metal cutting I am afraid. They would be great for cutting out knife scales and such, but for cutting stainless steel... a no no, even with a top of the line scroll saw......As for a band saw, all you need is a good metal cutting blade ( blades are more expensive than woodcutting blades ), use some cutting oil and take it slow. I have seen very thin metal band saw blades. Some advise is I would look at several modes. Ryobi makes OK stuff, but if you plan to use it alot, I would look for a better, more heavy duty machine. I have a craftsman benchtop band saw that I have used for wood, metal, and it has never failed me yet and I have had it for many years, I believe I got it when they first came out. Its made of steel plate and is pretty heavy duty. I think its under $200.00. it certainly will pay to look around a bit and do some reasearch on the net. Go to the stores informed because chances are, you will not more about the product on the shelf that the people selling it !!!
When I made knives years ago, I cut the blanks out with a hacksaw. I was one of the lucky guys that can cut a curve in metal with a hacksaw.....its an acquired skill....lol. My grandfather gave me some hacksaw blades made by "HELLER" and they Cut Anything & Everything. Zipped through 440 stainless like butter. I dont know if they are still in business.
The blade says:
High Speed "M" - HAX Hard Edge
12" - 18T No. 31E-1218

After reading through the posts and funds permit, I definately would recommend the Ridgid Band Saw. I have several of Ridgids tools, they have a lifetime warrenty and are built tough. I always research out everything and read reviews before I make a large purchase like this. I have a Ridgid table saw, drill press, drum/belt sander- bench model and a planer. As soon as I get my shop built, I am getting a Ridgid Band Saw for sure. I think the Ridgid band Saw is in the $400 range.
