Hi, Alexander,
Nice sword you made!
For casual use, just about any scrollsaw would be fine.
However, the throat of the saw (the distance from the blade to the back of the arm)
can limit how long your project can be so, you will probably want to buy a scroll saw
bigger than the small 15" or 16" inch saws.
For comfort, you may want to avoid saws that require a tool such as an allen wrench to
change blades. It is just more frustrating using a tool than to use a scrollsaw that has
knobs to change the blades with just your fingers.
If used a lot, parts do wear out on the saw so, you may want to be sure you can get
replacement parts nearby and easily.
Good luck with your choice and God Bless! Spirithorse
